it's fake that there is no English logo under the trademark of the polo shirt made in Vietnam. The main logo of the authentic polo shirt should be a blue logo with silk luster, and the English letters embroidered on it should also have silk luster, so it is fake that there is no English logo under the trademark of the polo shirt made in Vietnam. The Polo shirt was originally called a tennisshirt, which was originally worn by nobles when they played polo, probably because they were comfortable and liked to wear short-sleeved clothes with collars. Over time, it was called "polo shirt".
