Racerback wrap one piece

This was my first swimsuit project. The toile fit surprisingly well; I shortened the length 3/4" and graded from larger bust-waist to smaller hip. The finished suit fits very well; I made the built in bra, love the racerback (though I added a back waist seam for better fitting of my back arch). Couple of things I would change next time (and I will sew another): I found the ruching on the outer layer is a bit too voluminous and I had used quite a sturdy swim fabric so I would reduce the volume and/or use much lighter fabric for that layer, also I would use 1/4" elastic not 3/8" as it provides a bit too much structure. The elastic lengths as instructed for arms and legs, neckline etc, fit beautifully. Overall, I'm very impressed with the drafting and the instructions and video (the built in bra is a bit complex, wise to baste and not serge until you check everything).
I am pleased to have a great fitting fashionable suit! (Color-blocked solid navy with orange contrast underlay.)

Nice easy-ish sew

Have made 2 of the bikinis and am very pleased with them Great pattern!

Best swimsuit ever

I love this pattern. I was a bit nervous about making swimwear as I have never done so before. After watching the excellent video that goes with this pattern I had the confidence to give it a try. I made the bikini version and was very pleased with the result. I wore it to the local swimming pool twice and on both days I received spontaneous compliments about my bathers (swimsuit), and I am over 60 and don't look like a fashion model. I used some Liberty swimwear stretch fabric for the outer and power-mesh for the liner.
