Definitely order up in size rather than down. I got the 3x-4x size. It is pretty tight across the chest but it does show a nice bit of cleavage. The skirt is weird for sure. It's super long in the front then way short on the sides. The skirt is see thru fabric over a lining but the lining is very short, my butt will barely be covered, so I'm opting to wear some matching pettipants underneath to keep it PG-13. It's really pretty. Havent tried the headdress or bracelets on yet but im.sure they'll be fine. I cant wait to wear it to a burner festival I'm attending next week.
