Where can I get a knitted hat in Hong Kong?

You can surely find one in "Ladies Market" (Mong Kok).

Here's how to get there...
Take the MTR trains and get off at Mong Kok MTR station then take Exit E2. Take the Nelson Street exit and walk two blocks.

More Hong Kong good shopping places in here...

anyways have fun finding it

providing you go during late autumn to winter. You'll see beanies being sold everywhere...pretty much all shops along the street will be selling beanies..and most of the time will have knitted ones sold too. There's really no need to find a specific shop name or address....you're bound to find one easily.

you could try

1) women's street in mongkok

2) temple's street in yaumatei/jordan

3) bow ring street in jordan
