Creating your own swimwear is an exciting project, but choosing the right fabric is key to getting a comfortable, stylish, and long-lasting swimsuit. Whether you’re sewing a bikini, one-piece, or rash guard, the fabric you choose will determine how well it fits, stretches, and holds up to all your activities.
What to Look for in Swimwear Fabric
Swimwear fabrics need to be:
Stretchy: Look for at least 50% four-way stretch to ensure a snug, comfortable fit.
Quick-drying: Fabrics that hold moisture will feel heavy and uncomfortable.
Durable: Strong fibres prevent sagging and wear.
Top Fabrics for Swimwear
Nylon Spandex (Polyamide Spandex)
If you’re looking for a classic, go-to swim fabric, this is it! Nylon spandex is soft, stretchy, and fits like a dream. It moves with your body and gives that smooth, second-skin feel—perfect for bikinis, one-pieces, and even swim leggings.
Pros: Soft, lightweight, and dries quickly
Cons: Slightly less chlorine-resistant than polyester blends
Stretch: 4-way | 80-90% cross-grain and straight-grain
Polyester Spandex
If you’re planning to swim a lot—as in, lap after lap in the pool or back-to-back beach days—this is the fabric you need. Polyester spandex holds up like a champ against chlorine and UV rays, meaning your swimsuit will stay vibrant and stretchy for the long haul.
What we’d grab? Swim Print | Porcelain Rhapsody. This print has such a soft romantic vibe and just the right amount of stretch to keep things comfy.
Why you’ll love it: Long-lasting, fade-proof, and feels great against the skin.
Keep in mind: It’s not as silky-soft as nylon, but it makes up for it with durability.
Textured Swim Fabrics
Want to take your DIY swimwear to the next level? Textured fabrics are where it’s at. Whether it’s ribbed, waffled, or jacquard, these fabrics add a unique, high-end look to your swimsuit.
What we’re obsessed with?Swim Basic Rib | Marine. Navy is a timeless, elegant color that never goes out of style.
Why you’ll love it: Looks stylish, fits like a glove, and makes your DIY swimsuit feel designer-level.
Pro tip: Ribbed swim fabric provides amazing compression by hugging the body with its structured texture, creating a flattering and supportive fit.
Don’t Forget the Lining!
No one wants a see-through swimsuit, right? For a pro finish, always add a good lining. It keeps things secure, adds comfort, and makes sure your swimsuit lasts!
What we’d use? Swim Lining | Nude . It’s lightweight and stretchy enough to move with you.
Why you’ll love it: Gives your swimsuit that polished, high-quality feel.
Pro tip: Use Power Mesh if you're looking for tummy control in a one-piece!

Why Scuba’s Having a Major Fashion Moment
It’s official: Scuba is everywhere, and we’re not mad about it. Originally loved for its performance qualities in activewear, this luxe, stretchy knit fabric has now crossed over into elevated streetwear and even business wardrobes. With its smooth finish, structured drape, and durability, scuba is the secret sauce behind that modern “pulled together but still comfy” look.
You’ll spot it in sweatshirts, joggers, mini skirts, but also blazers, trousers, and sculptural dresses — all pieces that demand some structure but still move with you. If you’ve ever worn something in scuba and thought, “Why does this feel expensive?”, it’s because… it kinda does.
Let’s dive into where we’re seeing it, how it performs, and some sewing patterns so you can make your own.
Where Scuba is Showing Up Now
🔹 Athleisure with Edge
Scuba gives sweatshirts and joggers a crisp silhouette that elevates even the laziest outfit. Unlike slouchy fleece, it holds shape — think half-zips, funnel necks, panelled joggers, and sporty skirts. We’re also seeing scuba leggings with contrast seams, and sleek two-piece sets in monochrome hues.
🔹 Streetwear & Everyday Cool
Mini dresses, boxy tees, oversized sweatshirts — all getting the scuba treatment. It creates that “structured chill” look — less slouch, more sculpt. Perfect for transitional pieces that move from brunch to errands to low-key drinks.
🔹 Business Casual 2.0
This is where it gets fun. Scuba is being used in blazers, trousers, shift dresses, and even structured tops — all the looks of tailoring without the rigidity. You get that polished finish, but it stretches and doesn’t wrinkle easily. Basically: it’s your business outfit with sweatpant energy (but no one will know).
Why We Love It: Luxe Feel Meets Low-Maintenance
Sculptural Structure: Scuba holds its shape, making it ideal for dramatic silhouettes — boxy cuts, peplums, flared hems.
Stretch & Comfort: It has built-in give without sagging over time, meaning it moves with your body (hello, long work days).
Wrinkle-Resistant: Great for travel or pieces you just want to throw on and look like you tried.
Smooth Finish: Feels soft, slightly spongy — gives off major “designer” vibes.
Durable: Doesn’t pill easily, can handle wear and tear, and holds color beautifully.
Our Scuba Picks at Fabric & Flow
Not all scuba is created equal—and we've got two favourites in the shop, each with its own vibe:
Lightweight Poly Scuba
This one’s soft, smooth, and slightly springy with great drape—perfect for flowy sweatshirts, fitted dresses, or structured tees that don’t feel too heavy. It has that classic scuba feel but in a more wearable weight for all seasons. Available in Creme and Tabacco.
Cotton/Poly Scuba Blend
A bit heavier and more structured, this version has a softer, more matte surface (thanks to the cotton) and just enough body for things like blazers, wide-leg pants, and trench-style jackets. Holds shape beautifully and feels luxe to the touch. Comes in four colours.

We’re continuing our Community Spotlight series with someone who brings equal parts heart, skill, and honesty to every make — Leah. From her early quilt days to designing patterns and building a wardrobe that fits her, Leah’s sewing journey is full of intention, growth, and a whole lot of denim. Let’s dive in.
Hello, Sewing Friends! My name is Leah, and I'm a mom, sewist, pattern designer for Greenstyle Creations, Orange Theory coach, pattern hacker, and avid reader/ audiobook listener. You can find me on Instagram, rambling about all things sewing related, posting two-line book reviews, and sharing random bits of my life in my stories.
How did I start sewing?
I started sewing back in college, piecing quilts with a machine I borrowed from my mom. I wasn't into partying, so I would spend weekends making pillow cases and simple blankets. (I hesitate to call them quilts, because I never topstitched or properly bound any of them.) My mom still proudly displays those projects in her house, much to my chagrin.
I took a long break from sewing, but picked it up again right before I got married. I wanted a (popular at the time) bag made out of my soon-to-be husband's ACUs, so I bought one on Etsy. When it arrived, I had the classic "I can make that!" moment; I returned the bag, designed and made my own, and then proceeded to start making them and selling them to my other Army-spouse friends.
I started sewing apparel when my son was a toddler, making him a basic t-shirt pattern from Brindle and Twig. The first one was... not good. I'm pretty sure I cut it with the grainline running horizontally; I didn't even know there was a difference. I sewed solely for him for the first few years; I think I was intimidated by how much fabric was required for an adult pattern, compared to a child's make.
The first thing I made for myself was a raglan-sleeve shirt I found a free pattern for on a random blog. It also wasn't great.
Favorite thing I've made?
I can't think of one item that is my favorite. However, my favorite things to sew are jeans and button down shirts.
I sewed my first pair of jeans (Morgan Jeans from Closet Core) long before I had the skill or knowledge to be sewing them. I made them out of a terrible denim fabric from Joann’s that grew three sizes within an hour of putting them on. My second attempt five days later with a Cone Mills denim was MUCH more successful. I would probably cringe at the craftsmanship today, but I'm still impressed with myself for jumping into the deep end of sewing without fear.
My favorite quote for sewing is, "There's always more fabric!"
I love sewing jeans because I could never find a pair of ready-to-wear that properly fit me. Having the ability to sew up garments that fit me and my shape without a size label was so liberating. As someone who had always struggled with body acceptance, making clothes that were just "me-sized" and fit properly at every body point felt like a super power. It gave me the drive to create a nearly 100% me-made wardrobe.
Something I hesitate to make?
I've wanted to make the Jasika Blazer from Closet Core for years. I hesitate because I don't think I actually have anywhere to wear a piece so structured or formal. Also, I can't settle on a fabric that I know I will wear enough to warrant such a technical and time-consuming project.
I've also never sewn a pattern with shirring. I'm not sure the technique works with my overall aesthetic, but I'm always impressed by makes that incorporate it.
Skills to tackle this year?
I've been focusing on slower, more thoughtful construction and cleaner finishes. It's tempting to rush just to get a project done, but I'm always happier with the finished product when I go the extra step for a professional look and "pretty guts."
I love incorporating those extra elements into the patterns I design. I know a lot of folks balk at the concept of trying to make garments look RTW, but it's my personal goal to construct clothes that the average observer can't guess are me-made.
And, of course, I want to continue to improve my drafting skills.
Her Go-To Patterns: Denim & Button-Downs
Since Leah mentioned that jeans and button-down shirts are her favourite things to sew, we had to ask — what patterns does she reach for again and again?
Here’s what she shared:
Jeans: Closet Core Morgan (obvi) and Ginger(I'm not sure you can even buy Gingers anymore because they released the Judes, which are super similar, but more flared.)
And don’t worry — we got you, girl. We checked, and yes, the Ginger Jeans are still available at Closet Core!
Button-downs: Grainline Archer Button Down for more fitted look. Hey June Cheyenne Tunic or Amherst Shirt for more relaxed vibe.
It’s clear that Leah knows what she loves — approachable, well-drafted patterns with just the right balance of structure and everyday wearability. Whether you're sewing a classic button-up or tackling your first pair of jeans, her favourites are a great place to start.
Leah’s story is one so many of us can relate to — navigating body image, struggling to find clothes that truly fit, and then discovering the power of making garments that are ours, in every sense of the word. What makes her journey so special isn’t just the beautiful pieces she creates, but the confidence and self-acceptance she’s built along the way. Her size doesn’t define her style — she does. And that’s exactly the kind of reminder we all need sometimes.
Want to dive deeper into Leah’s jeans-making journey?
She’s shared more about her process on Instagram—especially how she combined two patterns, swapped a button fly for a zipper, and fine-tuned the waistband for a personalized fit (because sometimes you have to geek out on zipper installs!).Check out the full breakdown in the highlights on her IG page.
Athleisure isn’t going anywhere — but it is evolving.
This season, two fabrics are making waves: cozy fleece and sleek, structured scuba. We’re seeing scuba in sweatshirts, joggers, skirts, and even dresses all over in fashion, giving a sharper silhouette than your classic fleece gear. In this post, we’ll dig into current trends in colours and styles, how to style fleece and scuba for different vibes, and even share sewing pattern ideas so you can make custom pieces. (Heads up: the next blog will go deep on scuba—why it’s having a moment, its technical pros/cons, and more pattern recommendations.)
🔥 Trend Spotlight: What’s Hot in Fleece & Scuba
Fleece: Cozy, Textured & Eco-Minded
Fleece is still a cold-weather go-to, but 2025 is seeing a shift toward recycled blends and elevated textures. Think earthy neutrals like camel and greige, with pops of butter yellow or pistachio green. Oversized fleece pieces with abstract prints and zippered details are everywhere — comfy but cool.
Scuba: Sleek, Structured & Surprisingly Versatile
Scuba is stepping out of the "tech wear" box and into streetwear. You'll see it in sweatshirts, joggers, skirts — even dresses — with a clean, modern silhouette. The appeal? It holds its shape, smooths over lines, and makes basics look intentional. Trending colours include soft greens, muted rusts, and bold block tones. Perfect for that “I tried, but didn’t try too hard” look.
Style directions: dress up, dress down, mix fabrics
Here’s how to flex these fabrics in your wardrobe so pieces feel more than just “comfy clothes.”

Piece + Styling Tips
Fabric Choice
Notes / Hacks
Chic casual / elevated errands
Scuba sweatshirt (half‑zip or funnel neck) + tailored joggers or slim pants + chunky sneakers or mules
Scuba
The structured nature of scuba helps maintain shape under layering.
Layered cozy
Oversized fleece hoodie over a lightweight base + leggings + a longline coat
Fleece outer, lighter jersey / athletic inner
Use fleece as outerwear and let scuba or technical fabrics do the next layer in.
Loungewear elevated
Fleece joggers or wide-leg sweat pants + scuba crop top or fitted tank
Fleece pants, scuba, ponte or jersey top
Mix textures: matte fleece vs smooth scuba gives visual contrast.
Weekend dress-down meets brunch
Scuba skirt (mini or midi), hoodie or sweatshirt tucked in, chunky boots
Scuba skirt, fleece or scuba top
Use scuba for the bottom to keep neat lines even if top is relaxed.
Streetwear edge
Layer a scuba sweatshirt under a denim or leather jacket; pair with cargo joggers or scuba pants
Scuba top, structured pants
Because scuba resists wrinkling, layering works well.
Styling tips in practice:
To tone down a bold red or electric color, balance with neutrals in bottom/hats/shoes.
Use monochrome layering (e.g. different textures of similar hue) to make the look more cohesive.
For transition seasons, choose lighter-weight fleece or thinner scuba so the layering doesn’t bulk.
Add small details (contrast piping, colour-blocking panels, tonal zippers) to elevate a basic fleece or scuba set.

Sewing & Fabric Tips
For fleece, use a good ball‑point or stretch knit needle; serger or stretch stitches for seams.
For scuba, pay attention to edge finishing (it doesn’t fray much, but sometimes can have bulk). Use a walking foot or stretch stitch so seams lie flat.
Consider stabilizing shoulders or necklines with lightweight elastic or stay tape, especially in scuba to prevent distortion.
When mixing fabrics, remember they may need different seam allowances or handling care.
Always make a muslin (or test piece) if mixing heavy scuba and lighter fleece so proportions and drape work.
Takeaway
Fleece and scuba are both having serious moments in the athleisure space right now, each bringing different strengths: fleece for warmth and comfort, scuba for structure and clean lines. The key is knowing how to style them, layer them, and even create your own versions via sewing.
