>Women are a passive gender, so the way they dress is one of the few ways to send a signal.

>Is there a way to look at girl in a cute pink dress and tell whether she is there to just present a tech topic or she is also open to potential dating?

Why are you combining your search for a partner with work/conference. How about you assume no one is there looking for a date?
