Why on earth would you come to HK wanting to buy bras over a C-cup? (Unless you forgot to pack yours or something)

There are many great things to do here. Shopping for Caucasian-size clothes is absolutely not one of them (with the possible exception of custom tailoring, but even that isn't the bargain it used to be).

As a large Caucasian HongKonger I basically buy all my clothes online from the US or UK.
