okay imagine the most attractive woman you can think of in black and white. now first imagine her with blonde hair< whichever shade you prefer. now imagine her with beautiful red hair, fake or real, dont care for either one. now. which do you prefer?
okat sorry that might not make sense, when...
i would not advise that.. trying to look proffesional and casual at the same time? wear dark jeans, a t shirt a jacket and a pointy flat make sure your clothes match
hope it helps :)
