Throughout the 1980s and ever since in Japan, T-shirts have flourished as a personal expression.^[11]

T-shirts with bold slogans were popular in the UK in the 1980s.

Since the late 1980s and especially the 1990s, T-shirts with prominent designer-name logos have become popular, especially with teenagers and young adults. These garments allow consumers to flaunt their taste for designer brands in an inexpensive way, in addition to being decorative. Examples of designer T-shirt branding include Calvin Klein, FUBU, Ralph Lauren and The Gap. These examples also include representations of rock bands, among other obscure pop-culture references.

Screen printed T-shirts have been a standard form of product advertising for major consumer products, such as Coca-cola and Mickey Mouse, since the 1970s. However, since the 1990s, it has become common practice for companies of all sizes to produce T-shirts with their corporate logos or messages as part of their overall advertising campaigns.

The early 2000s saw the renewed popularity of T-shirts with slogans and designs with a strong inclination to the humorous and/or ironic. The trend has only increased later in this decade; embraced by celebrities, such as Britney Spears and Paris Hilton, and reflected back on them, too ('Team Aniston').^{[citation needed]}

The political and social statements that T-shirts often display have become, since the 2000s, one of the reasons that they have so deeply permeated different levels of culture and society.^{[citation needed]} The statements also may be found to be offensive, shocking or pornographic to some. Many different organizations have caught on to the statement-making trend, including chain and independent stores, websites, and schools.

A popular phrase on the front of T-shirts demonstrating T-shirts popularity among tourists is the humorous phrase "I did _____ and all I got was this lousy T-shirt." Examples include "I went to Las Vegas and all I got was this lousy T-shirt." and "My parents went to San Francisco and all I got was this lousy T-shirt."

T-shirt exchange is an activity where people trade their T-shirts they are wearing. Some designs specifically write on the shirt "trade with me"
