Guys, be honest. Describe a perfectly gorgeous/hot girl

This will be different for everyone. Beauty is in the eye of the beholder.

Its like justcurious55 said, beauty is in the eye of the beholder. Not every guy finds the same things attractive, and of course, likes and dislikes change as you grow up. For example, I like short girls with fair skin, who are smart and have a playful side. Personality is also a big factor, there's no way I could ever be with a girl, no matter how hot she is, if she acted like a stereotypical blonde lol
Anyway, its up to the guy and what they find attractive, not everyone likes bleached blonde hair and massive boobs :)
