Pattern Roundup: In The Swim of Things With Swimsuit Patterns

Recently, I shared with a friend one of the swimsuit patterns shown below. The model looks so comfortable and happy and confident. My friend remarked, “We should all enjoy our bodies in the sun and love our swimsuits.” 

Truer words were ne’er spoke. All of us want—and deserve—to feel great in our swimsuits. Do you want the perfect fit? Try making your own swimsuit this year.

Unless otherwise noted in these pattern summaries, use swimsuit fabric that includes spandex with four-way stretch. Also use four-way stretch lightweight knit nylon or polyester for linings.

Jalie's Zoe Swim Suit Pattern

Check out this long-sleeve, front-zip swimsuit in girls’ and women’s sizes. The Zoé provides plenty of sun protection in only one layer.

Friday Patterns Seabright Swim Suit Pattern

This one-piece swimsuit with plunging neckline can be made with or without sleeves. It has gathering at the shoulder and waist. If you prefer more coverage in front, there’s a tutorial for adding a lace-up neckline closure. Also consider this design for making a bodysuit, and use any type of knit with at least 50 percent stretch. Women’s sizes XS to 4X (bust 32 inches to 54 inches, waist 24 to 47 inches, hip 34 to 57 inches).

Half Moon Atelier’s Wells Bay Basic Bikini

Half Moon Atelier Bikini

This reversible, minimalist-style bikini takes full advantage of the stretch in the swimwear fabric. Rather than using elastics or other notions, you’ll create the straps by cutting and sewing fabric strips. However, you can use elastic at leg openings and other edges, if you prefer. The wireless top has underbust darts, narrow shoulder straps, and ties at the back. The bottoms are low-rise hipsters with curved side panels. These provide full coverage. The design lends itself to color blocking, so you’ll have lots of wearing options. Women’s sizes 1 to 10 (bust 30 inches to 44 inches, hip 34 inches to 48 inches).

Style Arc Summer Swimsuit and Top

Style Arc Swim Kids Swim Suit and Top

Three designs for children are included in this pattern: a long-sleeve one-piece (with or without ruffles at the leg openings), a swim top, and swim bottoms. The top is perfect for staying safe in the sun. It features a high neckband with back zipper. Children’s sizes 1 to 8 (height 33 inches to 51.2 inches, chest 21.3 inches to 26.8 inches, waist 20.8 inches to 23.6 inches, hip 21.3 inches to 26.8 inches).

    Why is no one making a pattern for skirted styles? Or with swim shorts (for women)? My favorite purchased swimsuit was Land's End tugless tank with matching swim shorts that could be worn over it. One day I intend to take them apart and duplicate them, but it would be nice just to be able to find a similar pattern.
