Homecoming dress

Wore to homecoming like 3 years ago, the dress is like a purple/ blue. I got this dress from kohl’s and it says the size is 7/8, but I’m a size 00/0 and it fits so I don’t understand. It is a really pretty dress, and it does have a bra inside! •Feel free to ask questions! •If you do not like the price, make an offer!!!
