When I blogged Leslie Arwin's Skeletees in 2007, I had no idea that I'd still be wearing my Skeletee all the time, six years later. But it seems like I wear it at least once every couple weeks, despite my massive trove of shirts. She does a gorgeous muscle tee, too, and many other designs:
Medical illustrator Leslie Arwin's Skeletees feature highly detailed, stark anatomical drawings of the bones, muscles, nerves and digestive tract, printed on the front and back. I picked up a skeleton shirt today and I'm delighted with it -- it's a great, thick, high-quality tee with a nice cut and the design is wonderful.
