A bowling shirt is a men's shirt that resembles an aloha shirt in construction, but not appearance, typically being more conservative and not incorporating tropically themed prints. They are loose-fitting, collared, short sleeved, buttoned shirts, with a straight hem designed to be worn not tucked into the pants. The fabric, color and design vary greatly, but frequently incorporate contrasting earth tones and simple geometric designs, with more expensive ones often made of silk. They may have a single breast pocket on the left—small logos or monogram initials are also common options on the left breast.
