The “Girls on Bikes” photo series by INSA has been re-blogged aplenty, but now you can have something to actually hold on to with the release of tees in collaboration with Addict. Unless your job doesn’t have a dress code, you won’t be wearing these tees to work anytime soon. There are bikes, boobs, and booty—two of which are red flags in the office. There are three shirts total, with one displayed above, and the two NSFW versions that can be seen and purchased on the Addict website. [addict]
