Why is the collar of a sailor suit so wide?

As the name implies, a sailor's suit is the clothes worn by sailors. The square towel above is suitable for keeping hair clean. Another way of saying this is that naval guns can stand up to help hearing and protect the eardrum when shooting. As for the white suit, it is more conspicuous in the dark. Later, it was officially adopted by the British Navy in 1859 as a formal suit for sailors. The origin of sailor suit comes from the clothing of the early British navy, also called deck suit. Later, it became popular as children's wear in Britain. At that time, the British navy was the most advanced navy in the world, so all countries followed its system and clothing style.
