Everyone should go on a shopping spree at Rockets and Rainbows.
This Etsy shop sells cutsey jewelry made with little nerd-friendly figures. There's a ton of Star Wars, but also My Little Pony (squee!). A perfect addition to a referential cosplay (Hipster Ackbar?) or just adding a little bit of flair to your work wardrobe.
