12 Swimwear Sewing Patterns to Sew in 2024

by Polina K

Whether you’re heading abroad or hoping for some good old British sunshine, it’s always smart to keep a collection of go-to swimwear in your wardrobe. But, with so many patterns to choose from, how do you pick your poolside look?

Luckily for all of us, the Good Fabric team has been kept busy finding the best swimsuit sewing patterns so that you don’t have to work up a sweat. From stylish bikinis to sporty one-pieces and everything in between, here are our favourite looks for the upcoming sunny season. Enjoy!

A Quick Note on Swimwear Fabric

Before diving into our top picks for your summer swimwear, we couldn’t not mention our go-to fave swimwear fabric, Econyl Nylon Lycra. We stock this super stretchy, sporty material in Standard, Light, and Swimwear Lining, and we highly recommend Econyl Light for your next swimsuit project.

This is THE best swimwear fabric of all time – hands down. With in-built UV protection and a huge choice of colours to pick from it’s the ultimate GOAT of seaside style. It’s also oil and sunscreen-resistant so you can wave goodbye to pesky stains.

Most swimsuit sewing patterns will also need a lining, and the handy Econyl Swimwear Lining fabric is a great choice to keep in your haberdashery. Or, if you’re looking for some extra support, use Econyl as main and lining for a double-whammy support.

For our expert sewists, the Hello Sunshine swimsuit sewing pattern comes with all the frills - literally! The triangle-shaped top is finished with super cute ruffles for an oh-so-girly look.

Coralie Bikini & Swimsuit by Tilly and the Buttons

A two-in-one pattern for sewists who like the best of both worlds.

When it comes to sewing swimwear, who said you had to pick between a bikini and a swimsuit? Have your cake and eat it too with the Coralie swimwear sewing pattern. Choose a one-piece with a high or low back, a bikini with high-wasted bottoms, or switch things up with low-waist bottoms and leg ruffles. You can also add an optional shelf bra and cups, making this one of the most versatile patterns on our list.

Looking to jazz up your shoulder straps? Look no further than the Kaia Swimsuit sewing pattern. A gorgeous twisted front gives a faux-halterneck illusion, before turning into standard, supportive straps down the back.

A built-in shelf bra adds to the support, and sewists can choose between a one-piece and a bikini for stylish swimwear.

Freya by Made My Wardrobe

Give your regular swimsuit a makeover with this figure-hugging one-piece.

The Freya Swimsuit pattern is the perfect choice for sewing simple swimwear that looks good. A flattering low back adds a little glamour to the swimming costume, while an optional cut-out on the front takes it from sporty to sun lounger-ready.

We love the adjustable straps on this swimsuit, too, and the tiny hoop details at the back are a winner!

Girlies who love to look cute while staying supported will adore the Vernazza Bikini sewing pattern. Providing plenty of coverage where you need it, you can swim, run, and frolic under the sun without worry.

Tank straps are ideal for bigger busts and the higher-waisted bottoms don’t skimp around the booty, while the tie front adds a flirty touch.

You can also turn the swimsuit top into a workout tank, which we think is pretty cool.
