This pattern is for a modest, one-piece swim dress with built-in leggings and a zipper in the back, which makes putting the swim dress on and taking it off easy and convenient. This pattern gives step-by-step instructions on how to sew the zipper, and also has a simple trick that makes it easy even for beginners with only modest skills. 

By making the swim dress all one piece, there is no danger of the top floating up from the leggings in water and exposing a bare midriff, no matter how wildly kids play in the pool, jump in, etc. This also eliminates the need for an elastic waist band on the leggings part. Most elastic typically gives out after moderate use due to the chlorine in pools. By not using elastic in the waist band, the lifespan of your swim dress will be greatly prolonged.

1 (size 18m, 2T) to 1.5 yards (size 3T and up) medium weight Lycra/spandex, 60" wide

1 zipper, 12" or longer

thread in matching color
