I love this shirt because anyone can wear it in public while her/his Star Trek fanaticism goes unnoticed. I bought this for my partner because I know he loves Star Trek (as do I) but if he goes out in public with a Star Trek shirt, he wants it to be subtle, so that only other Trekkies (or Trekkers, if you are one of those people) will recognize its relation to Star Trek. I personally wanted this shirt as well, for I love astronomy, but I only have so much money and I am a bit skeptical that a small size will fit my tiny frame. The large size plus the shipping totaled a little over $32. I would say it's worth the buy. Live long, my friends!
