This is Stretch & Sew 1260, a long OOP pattern that my mother sent me. I think she used it for my little sister, although I can't recall. The design is super cute - a basic maillot with an opening at the side seam, front and back ruffles and a low back.
The fabric is a tactel/lycra swimwear fabric from Chez Ami. It is really lovely. I've fought with some annoying swim fabrics in the past (hologram lycra, anyone??), but this stuff is nice and stable and easy to sew. I used swim elastic from Sew Sassy, which I'm also very happy with. It is soft, but with good recovery.
I lined the front with a white poly/lycra knit. It is much beefier than swim lining, which made it a good match to the fashion fabric, not to mention far less annoying to sew. I love the awesome little buttons at the side seam. You can also see that I used a triple zigzag to topstitch the openings. I actually sewed all but three seams on my regular sewing machine. You totally don't need any special equipment to sew swimwear.
So, that was the good... The bad - This is not the style for Myra's *ahem* ample rear end. This shot was the only one (of many) that actually covered her little ghetto booty, and this was immediately after readjustment. And it isn't exactly the best coverage even then. The high cut legs resulted in a backside with really poor coverage, and Myra spent the whole time she wore the suit picking at it.
The final verdict? It really isn't wearable. Myra only spent about 15 minutes in it before she was ready to take it off. When I asked her what I should do to fix it, she said, "Make a new one." I think she's right about that.
