Stephanie from Swoodson Says shows how to adapt a basic onesie pattern to make it a “body double” style onesie. The body double style is essentially a t-shirt top with a onesie bottom. The onesie bottom is layered up under the top so the hem of the top hangs free. It gives the look of a t-shirt but with the stay-put feature of a onesie. Her tutorials uses the Lullaby Line Bodysuit and Lap Tee pattern, but this will work with any basic onesie patern. Go to Swoodson Says to see how to make one.
