I hate the misuse of the word “literally” but in this case I will tell you that you can literally wear the word “geek” on your sleeve. And you can do it with computer keyboard letters, too.
Etsy crafter pipix whips up these sweet tees. In addition to “geek” you can get N3RD, L33T,<B>, ShiftY, CtrlZ, or even a custom combination (max 5 letters.)
They’re currently sold out, but you can email with your choice for a custom tee. You can get the letters attached to the sleeve or the back just below the neck. Somehow they claim to be machine washable, which seems surprising to me.
You can get them in black or gray, and at press time these were strictly for the ladies. Sorry, guys. Although it’s probably for the best, as I would postulate that while this might work on a girl, whereas a guy would probably just get his a$$ kicked for wearing this.
