The most famous of T-shirts styles are crew necks, also known as classic T-shirts. These are T-shirts with a round circular neck. They provide excellent flexibility, and fit comfortably on your body giving you a toned appearance. They work well if you’ve got a long and narrow face with slightly sloped shoulders. It’s an easy-to-wear T-shirt that can work well with many different outfits. If you’re wearing a high quality T-shirt, that means it's made of organic cotton fabric which performs well as a protective undergarment because it controls moisture and temperature better than cheaper fabrics.
