Geeky clothes make great gifts, so the world can instantly see your friend's allegiance to the Rebellion. Or the Federation. Or House Gryffindor. (Though you'd better remember to keep in mind the tastes of that geeky pal—a Marvel fan might want a Tony Stark T-shirt, but he'd be less happy to wear a shirt emblazoned with the image of DC's Flash.)
Because of issues with sizing, clothes and shoes can be tough to shop for, so we've got some accessories, too. And best of all, some of these items are unisex, so if your opposite-gendered friend doesn't like your present, you can keep it for yourself.
