I'm a bit confused about the difference between a t-shirt and a polo shirt.

A t-shirt is a garment made of cotton or other material that is worn over the shoulders and arms, with sleeves that extend to the wrists. It usually has short or no collar, and is often printed with a design or logo. A polo shirt is a form-fitting collared shirt typically made from cotton, polyester, or other synthetic fabric. It features a rounded, notched collar and may be designed with a variety of decorative elements such as embroidery, appliqué, ribbing, and buttons.
