Buy the Child/Teen Bahia Swimsuit sewing pattern from Petits D’om. Version A has a round neckline and straps that are an extension of the body. Version B has a straight neckline at the back, a very slightly rounded neckline at the front, and thin straps which cross or not at the back. For each version, you can make a one-piece swimsuit, two-piece swimsuit with a long top, or two-piece swimsuit with a cropped (bra-like) top. Each version can also be embellished with a ruffle or skirt at the waist, resulting in about 30 different combinations! This swimsuit can be sewn with a sewing machine or an overlocker.
