I was excited to try this out - I love a good maxi dress, but this isn't really cut like a maxi dress (and I don't think it's described as one either, but has the appearance from the photos).
I'm normally a size M or L, depending on brand... and how I want things to fit. This is big, but a little tight in the chest area (I'm a 36 C)... The buttons are also in an odd place at the top...
The fabric isn't soft and it's a bit scratchy/rough. The pattern (Floral) is pretty and bright, but the fabric doesn't feel great to the touch. I washed it and the texture didn't change... it didn't shrink either, which is good.
It is very flowy and if the top part fit correctly, an M would work well.. the skirt part is VERY flowy. It would be a pretty spring or summer dress, but the cut of this dress is just very odd sadly.

Buy a size up. Chest is too tight

Cute, casual dress. It is more fitted than expected through the bust (I’m a 34 D). I will keep as I’m able to make adjustment at home. Removing the snap-close gave me the room I need to be comfortable. Will use fashion tape, if needed, for cleavage-decency. I do like that it is more fitted, provides a slimmer look. Will pair with cute sneakers this spring.

I'm a size medium, but could have used a size small. I'm 5'8" and 130 lbs (pants are a size 27 or 4/6 if that helps anyone) and I paired it with a cute lace leotard to wear underneath to make my boobs look fuller and absolutely loved the combination.
