You guys did great. The shipping on the other hand was bad...I don't know what happened, but it looked like one side of my package got eaten by a machine. Unfortunately, it shredded through the mailer, and the OKWISHING bag that some leggings were in, causing it to get runs and grime on it. Never seen anything like it, but kind of wish the order was in a box (again, I know it was the shipper).
