How can you tell the difference between real designer's clothing and imitations?

It's quiet easy really, you can just look at the quality of the clothing and the shop it is sold in. I would advise you to go on the internet to check out normal prices of the clothing, and if the designer clothing that you're going to buy is a lot cheaper than that, then you know it's fake. I would also advise you NEVER to buy clothes or anything from the market. It will break in a sec.
