When you’re looking at shirts, size is often an issue. Many designs can vary in size. At MailMeShirts.com there are operating in 4 different sizes – Small, Medium, Large and Extra Large. It can be a good idea to have a look at the size table before you choose your favourite shirt. The difference is mainly in the length of the sleeves and around the neck. When trying out a shirt you should be able to put just one finger in between the buttoned collar and your throat. The sleeves should preferably be about 0.8 inches (2 cm) over your wrists, so it is visible under a jacket sleeve.
