I'm 5'6" 150 lbs and ordered my usual Medium and the material in the midsection does not stretch. Final sale so I'm stuck with it. FN doesn't exchange for size. They really need to do better with their exchange policy. Not flexible at all .

I am so in love with this romper but unfortunately the back can’t zip up. I ordered a Medium and normally I would wear a medium and occasionally wear Large. I’m 5’3 and I weigh 180 pounds so if you’re in the same size range get a large.
