Brown satin a-line ball gown with slip

Reposhing this because it doesn’t fit. It’s a nice chocolate brown satin with a long flowy train-type thing coming from the waist, held on by a loop sewn in to one side. Strapless, has boning. I will throw in a petticoat I bought to make it fuller. I think it was originally a bridesmaid dress, but I didn’t wear it as a bridesmaid so I accessorized the heck out of it. Dress is size 10 US/12 UK; petticoat is size 12 US.
