Prom; pageant Dress size 4

Worn twice for a pageant (worn 10mins max), it’s a dark plum purple color tulle on bottom tht is layered to give it that poof effect, sequins on the top, w/an open back. No alterations. I’m not sure what the brand as I don’t see a tag other than the tag the store has on it which says it’s a size 4. My daughter was a 2 petite n it fit her, but was just a tad big but nothing noticeable (pictured in 1st pic). Paid $375 for this dress. Not Sherri Hill -I don’t think-no brand tag, for views
