The idea isn’t new, per say, but “Jason” puts a fresh spin on it with iwearyourshirt.com.

“In this up and down economy I’m outsourcing my wardrobe (namely shirts) to corporate america and you! I’m going to wear a different shirt for 365 days straight in 2009, take multiple pictures throughout my day and blog about it. Days are sold at “face value” so January 1 is $1 and December 31 is $365.”

The project is already getting some early press, and January is just about sold out. You can see the full calendar here and get more details about how it works here.
