All people will express their identity through the clothes they wear. Designs on shirts can act as billboards, advertising to people where you shop, what bands you like, or even what your favorite drink is. Boba Bliss in University Town Centre and Bobalicious in Mira Mesa both sell shirts with their logos on it. Also check out Rotem Studios online shop, with swanky 'Got Boba?' designs on them.
