Looking good when you go out is pretty damn important.
There isn't much else to say about this. This is what I normally wear when going out for the night, it's simple but stylish. The black shirt is great but it must be IRONED. An un-ironed shirt is not worth wearing, it's just a fact.
Normally I'll wear a pair of jeans rather than trousers of some kind as this works well with the shirt (hell they go with anything)
Oh and the hair is important too, but mine is shit today as I was working and it was raining this morning.
