Prom dress, fitted corset, long slit on left side, gold/yellowish

Hi🤗 ‼️ this is a prom dress from last year that Iam most definitely wishing to sell. I wore it one time only and only for a couple of hours. It is gold/yellow with a fitted corset at the front. Ima a small young woman so it was altered to fit my but originally it was a size 10 now it’s a small. There is a long slit up the left side of the dress. I’m not sure what kind of material it is. There is a slip in the inside. And the back is very corset like.
