Royal Blue Mermaid Dress (prom)

This is a beautiful royal blue prom dress. It has 3/4 sleeves with a v neckline with gorgeous bead embellishments at the waist. It is designed by Patra. Fully lined and has a back zipper. However, this dress is not in its original condition....I added the blue and silver beading around the neckline to spice it up a little, it really enhanced the beauty of the dress. This is a size 4 dress. I purchased it at David's Bridal for $ 250.00....I am asking $80.00 for it or best offer. This is a size 4.
