Reformation midi slip dress

Reformation xs black midi slip dress, made from 53% viscose and 43% rayon. For reference I'm 5'7 138lbs and it hits just below my knees. I'm usually a 6 in dresses at Artitzia, so this will fit a 0-4, xs-s. Love this dress, just doesn't hang like it used to! No flaws, great used condition.
