A breezy one-shoulder swim top finished with a self-fabric neckband, armhole band, and hem band, topstitched along every edge — sewn without a single closure.
This girls' swim top is cut from a single front and back panel, with the raw edges wrapped clean by a self-fabric neckband, armhole band, and hem band — no lining, zippers, or clasps required.
Sized from 3 to 10 years (98–140 cm height).
You can sew this top as swimwear — use biflex fabric. For a light summer top instead, choose a light-weight cotton lycra jersey.
Use a serger (overlock) to sew it. If you don't have a serger, replace it with a stretch stitch or zigzag stitch on your sewing machine. Use rubber elastic when sewing the swimwear version.
