There is no summer without the perfect lime shirt. This goes well with casual as well as formal look. For a casual look you need a casual shirt which means that the length should not exceed your waistline by much. Keep this one cotton because the purpose is to beat the heat. Alternatively, even linen works well. Pair it off with a dark shade of blue denims or chinos in shades of blue, brown, white and beige. Loafers or even flip flops will work. This shirt really goes well with all skin tones as well as the summer heat.
