Start your easy Star Trek costume with a printed t-shirt like the costume tees featured here. A simple all-over print top or Starfleet logo shirt makes a simple and effective costume look. Pair almost any top with a pair of black slacks for a super quick costume. Add accessories to enhance your look or keep it simple. T-shirt costumes are fun because they can be easily reused -- as a costume piece, Trek convention uniform, or new series premiere party outfit.
