Bridesmaid/prom dress

In fair condition doesn’t have size and I don’t remember what size it is I would say it would be a size 2/4 it was altered to fit me At the time I was 125 5’2 currently I am 138 5’2 and as you can see does not close length with no shoes is to the ground I used it with 3 inch heels as pic shows the bottom is pretty dirty not sure if it can get dry cleaned to come off
