[$69, Music and Sons]
It's tough to tell here, but this shirt — from a line of similar shirts — is something special.
Music and Sons' Music T-shirts allow you to easily carry your mp3 player while still looking fabulous (though I suppose the supposed fabulosity levels are debatable).
After slipping your device into the T-shirt's front pocket...

you connect it to the plug you find inside, and then connect the earphones (also included) to a separate plug in the collar.

Voila!
