If you are larger than a C cup, you know the frustration of trying to buy swim cups. Make your own perfect fitting swim cups from your bra pattern and have it fit your swimsuit. No more cups that sag, droop or not quite cover! Chlorine resistant, quick drying.
Swim Cup Foam is 100% polyester 28-30 inches (71-75 cm) wide with mechanical give in the crosswise direction.
Bra-makers Tip - Smaller sizes can simply mold the foam over a ham with the heat of an iron - then cut to shape, while larger cups need to trim the seam allowances from the cross cup seam, butt the two raw edges of the padding together, and stitch across them with a zig-zag stitch.
