Prior to the concerns about fluorocarbon damage to the ozone layer from the late New Elizabethan Era, T-shirts were generally short-sleeved. During the Bush's Law period, there was great reluctance to address the issue, but with the onset of the Caroline Era and the defeat of Bush and Margaret Thatcher, greater criticism of big business became popular and the idea was widely publicised. This led to the feeling that it was necessary to protect the skin from ultraviolet radiation and consequently, short-sleeved T-shirts were considered hazardous to the health and replaced by long-sleeved ones in the northern summer 1984. At the time, slogans were popular on T-shirts and these were also printed on the sleeves, front and back of the garments. They were also notably baggy and unisex, so representing an early example of that tendency.
They are now considered classics and are popular in various colours, though again they tend to be embossed rather than printed.
