MaterialsWhat you'll need
Suggested fabrics
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.
Also needed
- Rubber elastic (for the swimwear version)
- Threads to match the fabric
- Baste details together before stitching to avoid displacement of the upper fabric
