I visited Silk Street in December, and bought loads of great stuff. I was really amazed by the quality of some replicas(especially UGGs and Canada Goose ski jacket) cause I was expecting an outdoor market with cheap-looking "Guci", and "Loues Vuiton".

A tip for those who wanna buy stuff from Silk Street, without actually going to China:
go to silkmarket-online.com and tell them what you want to buy. They gave me a fair price and replied my emails on the same day.

Don't order too much at one time though, to make sure the package makes it through the customs.
