I made my measured size and I love the fit! It’s just perfect for a swimsuit, tight enough to not shift in the water but not at restricting, and very comfortable! The tankini’s straps felt supportive for me and stayed in place as I swam. The racerback bikini also allows for a great range of motion!
For these swim tops, I used swim fabric (the floral and the aqua) and swim lining (the lavender), which, if you haven’t used it before, is a kind of squooshy and soft almost net-like material. I also used regular white braided elastic. You can use swim elastic but I actually prefer the strength of braided, and it stands up to the water just as well.

To assemble the cami tankini’s shelf bra, I basted the swim lining to the front of the shelf bra at the sides, wrong sides together, and stitched a line down the center of the shelf bra in order to keep the cups on their assigned side. After that I treated the shelf bra front as one piece and followed the rest of the directions to assemble the cami!
For the cropped tank racerback bikini, I cut out the Maui tank’s shelf bra front and the racerback back in my floral swim fabric and just the front in swim lining, again with a small notch for the removable cups. I basted the swim lining to the front of the shelf bra, wrong sides together, all the way around. After that, I treated it like one piece and followed the directions to assemble the tank’s shelf bra.
