I'm a small/medium and bought a xsmall base on everyone saying it might be big. I took my chance and boy. I literally wasted money on this buy. Not flattering. Looks like a massive oversize shirt. Not dress! I'm 145 5foot5 and it still swallowed me up. Every purchase on Fashionnova in the last 5 years quality has been 5 stars. I always buy 20-30 things at a time and never ever needing to return because it all fits and looks perfect! The quality is very good quality on this item it just the way it look on me. Almost like a WISH order failed! You get what I'm saying! Buy at your own risk. Don't say I didn't warn you! I'm gonna give to my dog as a blanket it that big! 😭
