Sexy is your confidence level(1-100) divided by your dress size plus your bust measurement multiplied by your average "pretty" rating (on a scale from 1-10) plus or minus 50 points, depending on your clothes and hair color.(blond=10 brunette=5 red=7 other=5)(good is plus, bad is minus)
So what we have here is
c/s+b(p)<plusorminussign>50=S
OR
I'm gonna say you're looking for at least a score of 335.
Or we could just say if you're sexy , you know you're sexy. You don't need someone to tell you. Because you know you look good and you feel good and you walk with poise and flair and you know men are watching you because, damn, you're sexy!
