A beach shirt is a type of clothing typically worn in warm weather. It is usually made of lightweight, breathable fabric and is designed to be comfortable and stylish. The most common type of beach shirt is a TEE, which is a three-letter acronym for 'T-shirt'. T-shirts are usually short-sleeved and have a round neckline, making them ideal for wearing at the beach or pool. They come in a variety of colors and styles, so there is something for everyone.
