This dress is beautiful! So flattering and the material is good quality and comfortable. The back is super adjustable so I would size it more on how small your upper body is or how long you want it. I’m 5’2” 130 lbs and I ordered a medium and it fit good, but I could’ve gotten a small so it would be tighter around my chest. You don’t need to wear a bra with it either! And it shipped and arrived at my house in like 3 days.
