Hello and welcome to the Forum :-)
A simple answer to your question, search for it. I am serious.
One way to search is the search function in this forum. By doing so you could end up with
her. Give it a t ry and read the bro's report.
Another way to search is to head out to the Wan Chai bar scene. You probably have better chances with a Pinay or Indonesian girl from one of the bars. It's more likely for them to trim / shave comparedto a walk-up or Hotel Girl.
Lastly, you find a (working) girl you like, bring the shaving kit and convince her to shave and offer your help doing so.
Hint: you can also search for a White Tiger....
Good luck, have fun and report back.
