Sports jacket is an indispensable piece of apparel that every man must have in his wardrobe. A sports jacket can put together a great look instantly. If you are going to office, a grey colored sports jacket can be teamed with any solid color shirt, matching tie and a pair of black shoes. If you are going for a casual outing, it can be teamed with jeans and skinny khaki trousers. Sport it over a nice polo t-shirt. Instead of going for similar shades, go for contrasting colors. While most men prefer to sport solid jackets, patterns and checks have also become popular these days.
