Today's show is the final installment of the Planet Money T-shirt project.
In all, each shirt cost us about $12.42. We open up the books and explain how that breaks down — how much went to cotton, how much went to the workers in Bangladesh, and how much went places we would never have imagined.
If you're into spoilers, here's a graph that lays out all the costs. (Note: Many of these figures are estimates. It turns out, even when you're ordering 24,470 T-shirts, people won't tell you exactly how much everything costs.)
