You know what, based on my personal experiences and
observation:
1. I consider myself as a good guy. Dressed up nicely with tie and
suit during the day, and have gentleman manner (seriously). But,
since I often dress up somewhat funky, daring, or tough-looking,
with spiky hairstyle, bandana etc. during clubbing or hangouts in
weekends, girls find it more often than not seemingly more
attractive and alluring. I've been told that many times by many
girlfriends. So, dress up, young guns! And be confident. 
I can share some tips on getting ur girl - in a proper and
gentleman way
U gotta be sincere, tho!
2. Although girls may not necessarily look for 'bad guys' for
future life partner, but as casual hang-out buddy(s), they usually
go for those types - looking for wild and more liberated attitudes.

3. Believe it or not, men also do find 'naughty' girls or women
somewhat more attractive than the regular, casual, conservative
kind of gals. Unless they truly are looking for female partners
with motherly and homy characters. Calming. But not daring.
