Included Pattern

Your class includes a PDF copy of the Sophie Swimsuit pattern. With curvy seam lines and a 3-piece balconette cup, the Sophie swimsuit is both va-va-voom flattering and reassuringly supportive, a silhouette equally appropriate in the south of France or the neighborhood pool. The pattern comes in sizes 0-20, with 5 cup options per size.

View A is a classic one-piece with a pronounced hourglass shape and skinny elastic straps. View B mixes a bra-style halter tied top with an elegant high waisted bikini bottom. With a low cut leg and a full cup, both offer sexily modest coverage. Tap into your inner designer by playing with contrast fabric and colour blocking, and learn how to add optional underwires and foam cups to make the most supportive swimsuit ever!

"I made my first swimsuit using this class I was pretty nervous about swimwear, especially putting in an underwire, but the class made it so easy to understand. I'm super proud of my finished swimsuit, and I've gotten a ton of compliments on it!"

Great class!

I really enjoyed this course, how everything is explained and the swimsuit that I was able to make! I would definitely recommend it!

Great class

I took 3 sewing classes (Basic clothing, Jacket and swimsuit) with Closetcore Pattern - I enjoyed all of them and learned a lot. Highly recommended!

Amazing class

This class was so great I ended up making three swim suits, two of the two piece and one full suit. I used the class each time and they turned out fantastic. This course took the fear of sewing swim suit fabric away. Great class and would recommend it to anyone wanting to sew their own swim wear.

Gave me confidence

I would have never found the confidence to try my hand at sewing a swimsuit without this instruction. It felt like a one-on-one class, which is great when working with new materials and learning new techniques.

I just wish I went swimming more so it would make sense to sew up a bunch of swimwear.

Sophie Swimsuit

I've long wanted to make my own swimsuits and bras but was daunted at the prospect. Underwires, elastic, small seam allowances, stretch fabric - it all seemed too hard to tackle without assistance. Taking this course equipped me with the knowledge and skills to tackle swimsuit and lingerie projects and after completing my first Sophie Swimsuit, I have not looked back. Heather's pep talks and positive attitude inspired me to really step up my sewing game.
