I am obsessed with vintage style dresses. I have always wanted to wear them but could never find them in stores. I'm seeing several I like on mod cloth but I'm hesitant to order because a lot of the reviewers complain that the dresses are too short to be work appropriate. I'm petite, but I'm still worried. Also, how quick and easy are returns if I don't like something? I sure wish I could try stuff on first.
