APC
TST + Causeway Bay
A monolabel store owned by the IT Chain, you guessed it, it's a store dedicated to French brand APC. When we were in there there wasn't that much denim as it was sale season, but a very nice selection of their shirting and jackets.
LOI YAN GAI
Mongkok
Yes, the infamous Mongkok night market. It's got the big cheese factor but it might be worth walking down there and gawking at all the weird things on sale there. A good place to find a cheap bag if you're out of room due to the stupendous amounts of shopping you've done in HK.
