Free size, fits M to L. Only tried on once. I bought it on Rakuten for 3,800 yen for a trip, but the fluffy design didn't suit my body type, so I'm selling it even though it just arrived. The lines themselves are beautiful and I think it's easy to move in. Please use it if you like ^ ^ (Comes with a blue fabric belt) #ResortDress #LongDress #Sleeveless
