Girl With A Funny T-shirt

In the 1980s, thermochromatic dyes were used to produce T-shirts that changed color when subjected to heat. The Global Hypercolour brand of these was a common sight on the streets of the UK for a few years, but has since mostly disappeared. These were also very popular in the United States among teenagers in the late 1980s. A downside of color-change garments is that the dyes can easily be damaged, especially by washing in warm water, or dye other clothes during washing.
At the turn of the 21st century, designing custom T-shirts online became more popular. Popular websites began to use digital printing (such as Direct to Garment or DTG printing) to allow customers to design their own T-shirts online with no minimum orders. In the beginning, DTG could not print well on dark garments; however, with the help of some online T-Shirt retailers, printer manufacturers such as T-Jet have all but perfected the process, providing consumers with many more printing options.
