Ah, but watch what you get in the factory outlets.

My daughter bought some very nice DKNY pants in a factory outlet that had DKNY JAN as the logo instead of JEAN; she didn't notice until after we got home.

You can find knock offs in any street market in HK such as Temple Street or Women's Street.

I've also been told recently that Seoul is really the place to go for high quality knock offs. My one time there years ago, I bought a pair of Adidas sneakers from a street vendor which lasted close to 10 years with a lot of walking in them, although a bit scruffy looking of course, near the end.
