Couldn’t be more perfect
I purchased this in a Medium, which was absolutely perfect based on the measurements in the size guide. The short length is spot on and doesn’t ride up at all. I was also particularly happy with the way the shorts are hemmed, which makes them sit better around the thigh (e.g. doesn’t dig in). I had to remove the cups from the built-in bra as I have a fuller chest, and that made the top fit much more nicely. Highly recommend this In Motion Onesie!
