Sewpony “Cosi” Vintage Swimsuit (pattern test)

Good morning!! My latest pattern test was for Suzanne of SewPony It is her newest pattern the Cosi Swimsuit which is a vintage inspired one piece and two piece. She is such a sweet woman and I would love to test for her again in the future!

(I was not compensated for this review. I dedicated my time and materials to test this pattern and in return, received the finished final pattern.)

This was my first swimsuit that I have sewn and I did run into some issues. Not the pattern, but the fabric which is a nylon lycra is super slippery and hard to sew. I feel like without a serger, it would be really hard to get a professional look. My sewing machine (and a lot of machines) like to stretch the knit material leaving the seams all wavy and pulled out of place. It’s just a learning curve and something that can be accomplished. But like I said it was my first suit and a definite learning experience. I have plans to redo Sophia’s bikini top which is the part that did not turn out quite how I wanted.

The suit starts at size 6 months and goes up to a size 10. Its vintage inspired with the high waisted bottoms of the two piece. It has options of a one piece or a two piece with center ruching panels on either suit, peplum skirt, leg frills, halter straps or adjustable straps. A ton of different ways to make this suit completely your own. I did the two piece with ruching, leg frills and halter straps. I have plans for more in the future!! You can pick up the pattern here!:

It is honestly the cutest swimsuit I have seen and LOVE that I can make it for years and summers to come!!

Suzanne was super awesome and really involved in the whole testing process. She listened to all of the feedback from every tester and implemented any changes to make the pattern seamless and perfect.

Here is my finished suit and Sophia loves it! (The top is loose around top and bottom so I am going to recut and redo that whole piece)






Thanks for checking out my project!!


ETA: I’m not sure why the photos are so small! I will be back to add larger. Also it was a grey rainy day here when I took these.
