When ordering, I asked if the choice of size was correct, and got no reply. Sadly, the L dress is too big, and looks like I'm dressed in a potato bag. The quality and fabric are ok, though. Perhaps S size would be fine for my height and weight -- the dress is really enormous, not "oversize" look. 
Delivery took almost 2 months, couldn't track, but got the reply from the seller and order protection prolongation.
