Sequin One Shoulder Gown w/ Embellishments

Ordered in a size 10 and was absolutely the most unflattering dress. Runs extremely large or dress was mis-sized. Fits nothing like the picture. For reference, I am 5’10, 165 lbs with a 39 inch bust. I’m not sure if sizing din even two sizes would have made the fit any more flattering. Does not have a defined bodice and could possibly work as a maternity dress, but is definitely not a column dress, nor form fitting. Didn’t look or feel like a quality dress that I normally expect from MacDuggal.
