Dry-Erase Shirt

A shirt that's tightly knitted from a nice glossy plastic fiber (say, acrylic thread?). With cotton mesh venting at the armpits for both style and function.

Comes with three markers small enough to fit in your pocket, but big enough to make an impact. Write your message du jour on your shirt in the morning, and change it as your mood does.

Doesn't need to be washed - just stand in the shower for two minutes.
