Bridesmaid or Prom dress

Tried on but never been worn. Ordered as a potential bridesmaid dress, but would also work for prom. Pictures are unfiltered. Color is a tealy-aqua color, semi vibrant. Interior is like a satin material. Outer layer is something like a chiffon- pictured in last photo. (I cannot find a materials label) I paid over 300 for a similar dress from David's bridal... for something that was no better than this dress.
