Such a beautiful dress & fit! I wear both M & L (depending on material) this dress can be worn as pictured or a little sideways, personally I preferred size ways just because I’m tall so if i wore it as pictured it would be too short for me. I think large would’ve also worked for extra length in the front. It’s very comfortable & back part isn’t too long. For reference I’m 5’8 & 152lbs. Also the dress is velvet material

This picture is misleading because the dress is not this material
