About the Laminaria Swimsuit:

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.

Pattern Format:

The pattern is available as a .pdf or print. The instructions have 68 meticulous step-by-step illustrated instructions.
PDF: The .pdf includes separate printing layouts for home printing (8.5″x11″/A4 paper) and copy shop printing (A0/wide format paper). For the home print option, the exact pages necessary for each view and option are listed so you only need to print the pages necessary for your view and size. The home print version is a layered .pdf so you can print only the size/s you choose.
PRINT: The printed version comes in a 6″x9″ envelope with a stapled booklet of instructions. The pattern is printed on printer weight paper (not on tissue paper).
