Beautiful open back Formal and/or Prom dress💜

I wore this dress one time, and it was to a fraternity formal! It’s completely open back, and it flows. Such a beautiful purple. I’m 5’9 (didn’t wear heels) and the dress was a perfect length. So the dress would heels would also look amazing on someone who was shorter than 5’9 as well! It is a size small but could easily fit a medium since I normally wear mediums.
