Adding an asymmetrical ruffle: Swimsuit pattern hack

Add an asymmetrical ruffle

Watch out swimming pools here she comes! Earlier this summer I decided to launch into the world of sewing swimsuits. I bought a suit pattern with a really classic shape that I thought would serve me well over time. The best part about this kind of pattern is they are really easy to tweak and change to make your own. So I’m going to show you how to add a ruffle to this pattern or one of your own. Ready?

I’m using the Sun and Fun Swimsuit from Peek a Boo Patterns. I posted my first Sun n Fun suit HERE. I made a second, unblogged though if you follow on Instagram you got a peek, where I added some leg ruffles. It went ok, but it helped fuel my confidence in mixing up the pattern.

I suppose you could call this pattern a knock off? I’ve seen this style popping up in ready mades at the pool and thought it would be fun. I’ve added one asymmetrical ruffle, you could use these instructions to add one on each shoulder, or wherever the spirit might move you. Just remember to watch your stretch direction!

Terms below:

RST: Right sides together

SA: Seam Allowance

As a note here-my ruffle is only one and a half times as long as the length of the suit. I think it need a little more gather, so I’m giving you the twice as long instructions.

I think this is my favorite suit of the summer! And some more hilarious pictures of my little model….
