Well I can Say that we all have our own taste....
But in general this is what i have observe about them...
HK gal = too skiny, kinda pale sometimes, light make up and a bit reserve.
But boy does office ladies in central surely looks hot to me
Cali gal = usually with smokey ice kinda make up which will make you immediately notice that they are not hk gal. Looks more sexy and hot due to more sexier dress. More outgoing and have personality which will naturally caught your attention.
All in all, well each to his own brother
