"T-Shirt" is the first solo single released by Barbadian singer Shontelle from her album Shontelligence (2008). It is her second official single following the release of 2007's "Roll It" which was released only in select European countries. A remix, featuring The-Dream, is included on her second album, No Gravity (2010). The single peaked at number thirty six on the Billboard Hot 100 in the United States, but peaked within the top ten of the charts in Belgium and the United Kingdom. In the latter country, "T-Shirt" was certified silver by the British Phonographic Industry.

"T-Shirt" was sent to Mainstream Top 40 radio stations on July 15, 2008. Shontelle and her label gave artists a chance to release their own remixed version of the song, which was to be serviced to DJs with the winner promoted as a featured artist.

Speaking in February 2009 to noted British R&B writer Pete Lewis of Blues & Soul, Shontelle explained the significance to her of the song: "I really like 'T-Shirt' a lot because, when you listen to the song, there's a lot of elements in there that will definitely appeal to girls. Like even the strongest women at some point can have that guy in their life who, if for some reason you can't be with him, is gonna have that effect on you where you're not gonna feel like going out, hanging out with your girlfriends, partying, or doing ANYTHING. And, if you do miss that person, the best thing to have of theirs is a T-shirt! Because it usually smells like them and you can put it on, curl up with it - and kinda pretend the person is THERE!"

Nick Levine of Digital Spy gave the song 3/5 stars and said:

Steve Perkins of BBC Chart Blog also gave the song 3/5 stars and said:

The official music video for "T-Shirt" was directed by Mike Ruiz.

It features Shontelle in various scenes around her home mainly lying on a sofa in a T-shirt belonging to her partner who is away a lot. She wears it as a symbol of her missing him and chooses to stay at home painting, wearing his T-shirt rather than going for a night out with her friends. It shows her and her friends texting each other and her friends getting annoyed she is not going with them. The video ends with her boyfriend returning from his trip and Shontelle smiling.
