Cottesloe Curve swimsuit pattern
Cottesloe is the classic swimsuit set - one piece swimsuits and mix and match bikinis with wide shoulder straps, sleek athletic lines and good coverage. It began when summer was coming and I couldn't find a ready to wear swimsuit that fit well, or a bikini sturdy enough to survive a pool with three kids grabbing at me. The pattern is modular, so the views share pieces and are easy to mix, match and hack - consider it your swim block. I've worked hard to simplify the process, so it's a perfect introduction to sewing swimwear, all achievable on a regular sewing machine.
