I've never sewn swimwear before, but I wasn't optimistic about being able to find a RTW one to buy, so now was as good of a time as any to try it out. Fabricland still had some swimwear fabric and I found one that would meet with my daughter's approval.
I used Kwik Sew 2605. It included good instructions for sewing swimwear and good measurements for sizing.
I started with a size 4, lengthened it about 0.75", and took 0.25" off of each side seam (front and back) at the underarm, tapering to 0 at the waist. After basting it together and trying it on, I took in the CB seam 0.5" from the waist down and trimmed 0.25" off of the back sides at the hip, tapering to 0 at the waist. (Essentially, I made the side seams straight).
I really like the racer back as the last swim suit was always falling off her shoulders. I think I could have added more in length. We'll see how this one works while she's in action. Obviously, I made no attempt at pattern matching across the CB seam.
I self-lined the front, enclosing the crotch seam. The pattern instructions just have you line the crotch. The fabric I used was pretty substantial, but I think a lining is still a good thing.
I used a triple zig-zag stitch for the hems. Not the most professional look, but I thought it was the safest for me as a rookie. Next time, I'll try something else.
Next up: I have a few things in the works. We'll see which gets to the finish line first....
