***Update, a reader just alerted me to the fact that it's similar to Anthro's Rising Vapor Dress below.
This dress reminds me of a Gray Chiffon top or dress at Anthro. I don't remember the name of it, but when I saw this dress, it immediately reminded me of Anthro. I think I can style this as a dress or a tunic. On sale now for $29.99. Buy it here
