I started thinking maybe I should have upsized when opening the packaging. I am a very bottom curvy girl and the waist band is not very stretchy. I hopped into them and once I got the waist band over my cheeks it fit perfectly! I have a small waist so it was actually a good thing the waist band is a bit smaller. Once I got the outfit on, it was so comfortable! Very stretchy and form fitting. I was hoping the top would be a bit more oversized. If you want a more oversized shirt upsize. Overall I'm very happy with this purchase!
