Where can I buy designer fabrics like the ones fashion houses make?

Dear Mr. Know-It-All,
I am a big fan of your column. After all these years of reading, I suddenly got the urge to write in and ask you a question myself. Where can I buy designer fabrics like the ones fashion houses make? In the States there are a lot of retailers who offer that. Can you tell me where I can buy them by the meter?

Too stingy to pay for the real deal, but still want all the glory of being decked out in designer gear? Fair enough. Since you’re so committed to designer fabrics, I’m surprised that you haven’t heard of Sham Shui Po’s abundance of fabric shops, which really is much better than the Garment District in NYC or wherever you go to buy designer fabrics in the States. Visit Yen Chow Street and the fabric market on Yu Chau Street, where you will find more fabric than you will ever need in your life. The area draws in shoppers ranging from art students and fashion designers to bored housewives in need of justifying their fabric-oriented existences. Which one are you?
