Where online could one purchase cheap designer clothes?

carefully go through every charity shop and secondhand store you can find...its hard work but pays off.

also you can design your own and make them yourself...you'll have a one of a kind piece made specially for you

well, i think it depends on what age group your looking for. It also depends what gender. For people who are older i agree with going to second hand shops. For younger girls, there r a lot of websites like lovetoknow.com and about.com that can tell you the latest trends and coolest stores to buy clothes from. For younger boys, i would suggest visiting some websites.
