Wear not too tight but not to loose clothes. Make sure they are ironed. Make sure its not too long or short for your height. Also the colours should match your skintone. You can research based on yout skintone what colours bring out a glow in your face.
Make sure the colours are simple, so don't add more than 3 colours.
Leather jackets and jeans really go well
Also don't over do it or you will look effeminate, that's not a bad thing in itself. But personally I like men to have a slight edge or scruffy look, it comes across of as very charming.
