Dancing Queen Royal Blue Formal Dress

I wore this to prom and a military ball. It has a side zipper and is silk on the inside. I believe it is a size 8, but I cut the size tags off since they were itching me at prom. I size up in formal dresses, I’m a 34 G and the bra cups in this help me up and squished me in, so smaller chested girls would be great too. I’m sure it’d fit an actual 8 just fine. I never had it altered. It’s long for me and I’m 5’9”, wearing flats. Offers welcome.
