A t-shirt is usually only made of cotton, with a simple design and doesn't have a collar.
A polo shirt is usually a polyester/cotton blend (but can be found in cotton only). Polo shirts usually have collars and button up near the neck. Breast pockets are also common as are a horizontal striped pattern in the fabric.
