|The reason you haven’t heard of this costume is because you haven’t discovered it yet. Channel your inner pointy ears with this blue Starfleet uniform styled after Spock’s in the 2009 Star Trek Movie. The best part is, you could also be dressing as Sheldon, dressing as Spock. How meta. The solid construction ensures this wont be a one-time use costume and features an embroidered Starfleet emblem, and sleeve rings indicating rank. To select a size for women, match your measurements to the closest available mens size.
