Looking to dive into DIY swimwear this summer? Great news, you don't need to spend a ton to get started. Make a splash without spending a dime with these 5 free swimsuit patterns, perfect for beginners or experienced sewists looking for a new project.
Let’s dive into five swimsuit patterns free for you to use. We've included a mix of styles (bikinis and one-pieces) and tips on the best swimwear fabrics to pair with each.
Madalynne offers several free lingerie patterns that can be adapted for swimwear, including bralettes and coordinating bottoms. These patterns are a good option for sewists who want to experiment with bikini-style pieces, but you’ll need to use swim-specific fabric, lining fabric, and elastic.
The Oahu Swimsuit pattern is a polished one-piece with a flattering scoop neckline and a waist belt that helps define the silhouette. Its thoughtful details make it a great choice for sewists who are ready to take on a slightly more involved swimwear project.
This classic triangle bikini is a simple, versatile style that lets your fabric choice take centre stage. Although the pattern isn't completely free, it is still an affordable option for beginners who want to try sewing a basic bikini.
This girls’ swimsuit pattern includes a one-piece pattern or a two-piece pattern design. It's a practical choice for sewists who want flexibility and the opportunity to mix prints, solids and textured swim fabrics.
The Abelia pattern is a sporty long-sleeve one-piece that provides more coverage than a traditional swimsuit. It can also be adapted into a rash guard, making it a versatile option for swimming, surfing and active beach days.
Free patterns are a great place to start, but when you’re ready for a more polished and guided sewing experience, explore Fabric + Flow’s collection of sewing patterns.
Unlike the free sewing patterns, Fabric + Flow patterns offer a more complete and streamlined sewing experience. Each pattern includes clear step-by-step digital instructions, a copy shop file, a Letter/A4 print-at-home file and a projector file. You can also choose to download a digital pattern or a professionally printed paper pattern.
The Ease swimsuit pattern is a fun introduction to DIY swimwear. This bikini pattern has clean shape and straightforward construction, making it a great project for beginners learning the basics of how to sew their own swimwear and achieve the perfect fit. Use the same main fabric materials for both pieces, or pair a bold print with a coordinating solid to create your own look.

Free swimsuit sewing patterns are a great way to experiment, but Fabric + Flow patterns are designed to offer a more complete and guided sewing experience. Each pattern includes step-by-step digital instructions, an A1 copy shop file, a Letter/A4 print-at-home file and a projector file. Digital and professionally printed paper options are also available, making it easier to choose the format that works best for your sewing setup.
The amount of fabric you need depends on the pattern, size, style and fabric width. A bikini will generally require less fabric than a one-piece or long-sleeve swimsuit. Always check the fabric requirements included with your chosen pattern before purchasing, and consider buying a little extra for pattern matching or adjustments.
Both plain and patterned swimsuits can be flattering. Solid swimsuit fabrics can create a clean, streamlined look, while prints can add personality and draw attention to particular areas. The most flattering option is usually the one that suits your style, fits well and makes you feel confident.
Use a stretchy swim fabric such as nylon-spandex or polyester-spandex, and sew with a stretch stitch or narrow zigzag. Add swim elastic to help edges hold their shape, swim lining and power mesh for support, comfort and coverage.
Start by choosing a swimsuit sewing pattern that matches your skill level and preferred style. Gather swim fabric, lining, swim elastic, matching thread and a stretch needle or ballpoint needle. Follow the pattern instructions carefully, test your stitches on fabric scraps and take your time when attaching elastic and lining.
For an easier start, choose a Fabric + Flow swim kit with coordinated fabrics and essential supplies ready for your project.
