From Lily Sage & Co on Etsy:
VIEW A is a one-piece with high-waisted pants, tapered midriff, and a slightly gathered front bodice. The straps tie securely at the back and behind the neck in a halter style.
VIEW B is a high-waisted bikini with a simple halter neck top and two back straps. NOTE: these straps are designed to be positioned at least 4” (10cm) apart on the back when they are tied (not tied together as one).
The pattern accommodates blending different sizes for the bodice and pants in both views. There is plenty of opportunity to mix and match colours and contrast fabrics.
