Soft, stretchy and adorable! Beautiful crossover slit on the leg of the dress and thumb holes. This is a 2 piece set with *separate* shorts - it is not a onesie underneath. As with my other Halara listings, I am a size 10 and ordered a MED. I found it was slightly too small and opted to order a large instead, but I like my clothing to fit slightly looser than most. I’ve attached the halara size chart for a MED.
