When you’re not helping Captain Kirk on a mission in the starship Enterprise and are just hanging out at the Starfleet academy, petting your purring pet Tribble, you’ll need to dress down in these solid black threads. The Men's Star Trek Movie Shirt Black Costume looks just like the off-duty uniforms that Kirk and Spock wear in Star Trek: Into Darkness. It’s a two-piece, solid black uniform with a long sleeved top featuring a gray Starfleet logo embroidered on the left breast. The pants are the most comfortable in all the galaxy, but don’t get too comfortable! You’ll need to be ready at the drop of the hat to put on your red, yellow, or blue shirt when you’re called into duty to save the world from Klingons.
