Old navy pj romper

Never worn, new with tag old navy romper pj set. Fits big so it fits like a medium/large for that fitted look. Unless your thick than should fit tight, I’m on the slim size and normally wear medium as regular size, and for tight fit I can get away with xs or small. It’s super cute but doesn’t fit me how I would like. I’m 5’2 for reference and length wise it fit fine.
