It's the "A Dose of Buckley" logo, now available on a shirt! Exciting, I know, but listen, please don't empty your bank account buying too many of these. Also, if you're like "umm, where are the lighter colors, I hate dark colored shirts?" well, I have a different listing for those with black text instead (the white text looks terrible on a white shirt, trust me).
I put the leggings here as a joke because TeeSpring offers them. If you actually want them though... here they are.
