actually, I sometimes do this (even though I'm very far from a metrosexual male, I often don't shave for weeks etc). But if you wear something bright, interesting and quite different, it can help pick up chicks because it makes you look interesting, and makes you stand out from the crowd. Pink is over kill, and silly to wear lately since guys think it's cool... but a bright purple scarf will do the job, or something along those lines
(ps, this itemizing thing must be unique, and must be an accessory. pink shirts etc make you look like a toss)
Yeah my work line of clothes has a lot of whites/blacks.... you know, "goes with everything"
