ivory prom dress with gold beads.

it is a halter top dress. it was originally i believe a size 5 or 4. i had it altered to fit me im a size 2. it was also hemmed to my height i am 5ft 2in. it’s a hammy down. it has been worn once by me and once by another girl. it’s very simple and light. has pads in the chest. the alterations cost me 130$. there is no tag that i can find so i have no idea what brand it is or the exact size.
