From Tuesday Stitches:
The Laminaria swimsuit is a one piece swimsuit with a sinuous inset panel that wraps around the body like its namesake kelp. The pattern is fully lined and comes with 2 different cup size options (A-C cup or D-F cup) to make fitting a breeze. View A has decorative inset panels while View B is plain. Either can be sewed with a sharp V neck or an easier to sew rounded V neckline. Instructions are included for optional cup insertion. The straps can be tied around the neck halter style or can be attached to the back either straight down or crossed across the back.
