If you want a new outfit, you could easily keep to cheap plain clothing; for example, a long top and team it up with some nice shoes and one accessory.
Remember.. Sometimes less is more!
Exchanging clothes is obviously a good idea, as you can get rid of all your clothes you don't want and get new ones back in return so you're re-inventing your wardrobe without spending any money- great in this economic climate. But to my dissapointment it wasn't as good as it could have been.
