The classic white, non-iron, business shirt in a twill weave. Twill is an open weave that makes the shirt breathable.  Wear your favourite suit over this stylish shirt and tie a nice tie. The wide, soft collar falls under the blazer lapel to give you a beautiful and smart look. The shirt should be washed at 30 degrees without too much spin, and then hung to dry, so you don't have to iron it.
