Zara Maxi Dress

This long sleeve free flowing maxi dress is a 2 part garment.. the top shell is sheer with a mix of slate gray and light gray. From afar it almost looks navy. The underslip is black, full length and detaches from the dress. There is one fabric covered button on the front collar with pleats around the low hipline of the dress. This is an extra small but could fit a small. Dress has been worn but in mint condition.
