If you're proud of a particularly brilliant tweet, you might be able to wear it on your chest, thanks to clothes2order.com. The company, based in Manchester, is offering to print a tweet on a T-shirt in a competition it's running on Twitter: it will pick the best tweet submitted before 2.30pm every Friday and print it free.
Otherwise, having a single TweeShirt (sic) printed probably isn't economical. The set-up costs would be much higher than the cost of an unadorned shirt, so you'd need to order a few to bring the average price down. This might work for a party, a small company, or as a promotional device (somebody has probably tried business card T-shirts already), but your funny 140-character aside probably wouldn't be the most suitable text.
A clothes2order spokesperson says the company has no plans to sell TweeShirts at the moment, but if it added the option to its site, the estimated cost will be £12.99. It would presumably make sense to offer the same kind of feature on Facebook.
The @clothes2order Twitter account only has 26 followers at the time of writing, so there may not be a strong interest in TweeShirts. But I expect that lots of people with an interest in Twitter-based marketing promotions will be watching what happens.
Twitter already appears to have a deal with Threadless, where users can submit Tweets for T-shirts, but these tend to be slogans rather than personal comments. Also, unlike TweeShirts, Threadless's shirts don't use the Twitter message format.
