You'll board the Enterprise in a heartbeat once you put on the Star Trek Classic Adult Deluxe Blue Shirt. This is an officially licensed costume that actually looks like it could have came straight from the set of the classic TV series. The shirt is long sleeved and blue, with gold lining on the wrists and black lining on the neck. The shirt also features a gold comm link on the upper chest which is how the characters spoke to each other from a far distance. The color of the uniform depicted what branch of the ship you worked in. The blue coloring meant that you worked in the science or medical fields. These are the uniforms that were worn on The Original Series, making these very classic costumes. Wear these to a Star Trek theme party or to a convention to truly show it off.
