Vintage Shirt Dress

Says size 7/8, I'm going to say it's more like a 6. I'm a 2 and wore it once, but there was a lot of room in the chest area (i'm 34B) and it could stand to be shorter since I'm 5'2". Could fit a 4 also. Has an elastic waistband. It has so much potential, that's why I love it, but it is a bit big on me and I think someone else could definitely wear it better.
