For all the other reviews it is very true that the quality of the material is amazing for the price. It is really pretty even without an under skirt, just beautiful.
Yes, it is difficult to get your head through (put a scarf on if you're wearing make up) and yes it is difficult to yank over your chest if you are a little on the large size but once in place, it fits like a glove. I'm a size 10-12 UK and the Medium is perfect! No need for alterations at all.
I bought this for my brothers wedding at Christmas so I've loads of time to get creative to complete the ultimate vintage look.
