A dress shirt is a garment or a shirt that has a collar and a full front opening along the hem with buttons to fasten it together. Primarily used in formal settings it is seen often accompanied by a tie and a jacket. However a dress shirt can easily be dressed down as well making it a staple for male fashion for its ability to be both formal and informal depending the occasion. The fit is very important for a good looking dress shirt, a loose dress shirt is a look to be avoided, the fit should hold to your frame without being tight and restricting movement.
