Ok, I know these aren’t technically t-shirts, but they come from a t-shirt company, so hopefully that still counts. Teefury just put a whole set of ugly Christmas sweaters on pre-order. They will ship out on November 9th, and they cost $25.00 each, which is a pretty damn good price for a sweater (even if it is ugly).
This Peanuts inspired offering is my favorite–truly ugly, but in a charming way.
