Buy a Tee, Plant a Tree, a Toronto-based online retailer of vintage t-shirts, has partnered with in order to positively associate the company with environmental concerns.

For every t-shirts sold, the company will sponsor WeForest in planting a new tree. The connection, says Defunkd founder James Applegath, is that “vintage tees are green symbols because they represent the 3 R’s.” 

The virtual t-shirts shop does not deal in new t-shirts bearing old designs, but in actual old t-shirts, the prices of which range from five dollars for a c1980 “Hang Loose Hawaii” shirt, to $13,000 for a Run DMC My Adidas tee. Other pricey duds include a $2,000 dollar Eraserhead movie tee, and a $1,000 dollar glow-in-the-dark De La Soul shirt.

The money Defunkd donates helps WeForest alleviate poverty in developing nations by employing women to plant trees, often in places where deforestation has resulted from population booms and various economic pressures. Coincidentally, the site hosts an entire section of vintage Nike shirts; in 2009, the sneaker company vowed not to use leather produced in deforested areas of the Amazon. Paradoxically, the offers a vintage tee from the 1989 Kevin Costner film Field of Dreams, which was about cutting down a corn field to build a baseball diamond.
