How to Install Bathing Suit Bra Cupscomments (12) June 13th, 2011
4) Cut and pin a strip of 1⁄2-inch-wide lingerie-weight tricot around each cup edge to cover the stitching. Overlap the ends and straight topstitch 1⁄16 inch along both edges around each cup.
5) Cut a 1⁄2-inch-wide piece of picot-edge brushed-back elastic 1 inch shorter than the bra's lower edge. Mark the center. Pin the elastic, brushed side up, to the inside lower edge of the bra, matching center marks. Topstitch using a wide zigzag stitch and stretching to fit.
6) Install your bra before sewing your swimsuit layers together. Place the bra with the skin side face up on top of the right side of the swimsuit front lining, aligning neckline and armhole edges. Baste the armholes, neckline, and side seams. Zigzag-stitch to the front lining across the straps. The lining and bra will now be treated as one piece.
Set up your serger
If you're using a serger, use a three-thread overlock stitch with wooly nylon in the upper and lower loopers and polyester thread in the left needle.
No serger, no problem
On a regular machine, use a long basting stitch and a zigzag stitch with a stretch size 11 needle. A walking foot may help with all the layers.
Baste seams before sewing
To ease fabric handling and minimize fabric slippage, baste all seams before machine-sewing.
