This is a great dress, fun and flirty. I really like the exposed zipper. The only change I made was to lengthen the hem. I do wish that it was more fitted through the waist and hips. It's kind of hard to alter though, the way it's constructed is not straightforward. (It's not hard to make though.)
I like that the collar can be worn either up or folded down. Be aware that it is low cut in front.
