This is a simple, easy to knit, one piece bathing suit pattern for 18” dolls such as American Girl Dolls, Amazing Ally, Fancy Nancy, Springfield and other dolls with similar type bodies, the 18” slim body dolls such as Kidz ‘N’ Cats and 17” dolls such as Magic Attic. It takes very little yarn, so is great for stash busting and knits up fast.
