They let me try out the whole process, creating an account and creating a style profile with my sizing information that matched me up with girls my size who were selling their things. I picked out a few items, and then spent the day up at their showroom, digging through racks of their amazing designer pieces, and then creating an outfit.
If you have some unworn or unwanted designer pieces, anyone can sign up to sell on Shop Hers. They also have a VIP program where you send them your pieces and they price, photograph, list, and ship all your merchandise for you -- so easy if you have no extra time to do it yourself (like me).
Or if you're looking for some designer pieces to add to your closet, but don't want to pay full price, they're a great place to look. And to help you out with your first purchase, they're offering a $50 site-wide credit, available for 24 hours after you register...so hop on over and treat yourself to something fabulous!
