I wear all black sometimes: black jeans, black sneakers, black polo shirt, black belt, but with white socks.Danger said:The 'all black' thing is kind of iffy. One outfit that I wear for big events such as a major music night at the bar, or New Year's Eve, is black pants, shirt, jacket, belt and shoes, with either black or white socks. I have a really nice beige (not quite pink) tie that sets it off well.
Generally, sticking to 'earth tones' takes the guesswork out of it. Grey and black tend to go well with anything, and most shades of brown work together.
