go with greay man, i jus got my self a hugo boss suit. Its not pinstriped (solid charcoal color) and a black shirt with a solid charcoal tie, fukin hot!
but as for pinstripes i have a grey one, but with beige stripes. Grey sticks out far more than any other persons suit. Its more unique cuz where ever ur wearing it, theres guranteed to be atleast 90% black suits there.
