Windsor Prom/Formal/Bridesmaid Dress, Sage Green Size 3/4? Long, Open Back

This dress has been worn twice, once for prom and once for a bridesmaid dress. It is in good condition although I did have to sew the strap in the front to tighten it. I have pictures of it. I cannot find a size in the dress for some reason but my daughter usually wears about a size 3/4 and it does have a decent amount of stretch to it. It is a beautiful sage green that is so popular right now, and is a little longer in the back.
