I purchased this dress for a wedding that I was unable to attend. My loss, your gain! It's got the original tags attached and comes in the original packaging. I did open up the bag to take photos.
This bridesmaid dress is the Long Mesh with Cowl Back Detail F15933 style by David's Bridal in Petal. It has a V-neck, a cowl back, and is about ankle length. It accentuates the bust and flows freely from there. When I tried on the sample at David's Bridal, it fit comfortably with a standard bra.
