I've always thought of grey as a neutral color that can be worn with either black or brown for a decent look if you're too lazy to pick a more dynamic color to compliment black or brown (I'd never wear black with brown or tan/khaki), though I've run into a lot of people online who say that wearing grey with brown is a fashion faux pas because grey is "a shade of black" or something like that. On the other end of the spectrum, I've seen men who say that they only wear brown shoes with grey suits. Right now I was about to go out wearing a brown suede jacket, brown loafers, grey jeans and a grey striped shirt. Probably not the most exiting look out there but I didn't think think it clashed and the outfit colors match my hair and skin color (dark brown hair and light skin). Any opinions?
