Out of all of the possibilities, an extremely interesting Tshirts design is definitely the black concert Tshirt. As associated from time to time to black metal fashion or to punk fashion (normally common amongst rock lovers of all sorts), such Tshirts represent a fashion trend normally connected with attending rock concerts. The practice has spread in the seventies till the present day, thanks to all sorts of musical groups that resort to these as a kind of advertising. They either give these Tshirts away or sell them, in order to promote their band at all sorts of events including official releases and concerts.
