If you read the first two posts, which laid the ground rules you will know that the cardinal rules are; White shirt, Hair and Fit. Whatever your style niche is, you should look well put together.

One thing I will say is that even if don't care about clothes and dress like a children's tv presenter, do yourself a favour and smell nice. I don't care if you look like Ryan Gosling, stinking like a panda or smelling of 'eau d'you' is not really that attractive; and women love a man who smells good. For me, the holy grail of men's fragrance is 212 by Caroline Herrera; one whiff is all it takes and the transformation from dork to bonafide demi-god is complete. Don't believe me? Try it and see.
