Yikes. This dress started falling apart really quickly. The medium was honestly too big and I am 57 172lbs. It was crazy long, You cant wear flats with this unless you're 510+ and the quality is not there to bother hemming it.
It started freying as I walked the one and only night I wore it. I imagine this would be really cute for photos though.
Also: don't wash it in the washing machine. I read that in the reviews beforehand but my boyfriend did it  Now it is 100% unwearable.
