If it's hot outside, take off your shirt and flex.

As others have suggested, you could try starting a conversation
with her. If you see her on a repeated basis and she notices that,
it's a very good base for a conversation.
You'll have to gauge her personality - if she's chatty and
outgoing, it'll be very easy. If she's reserved...then you have a
bit of a challenge ahead of you.
...you could try to elicit an opinion from her. That's always
worked, but better do your homework and find something good and
interesting that capture her attention.
I don't want to mention any here on the forums....just in case I
end up in SG one day and some of the ladies here catch me.
