Here's a sampling of the outfits that were released at the very start of the "Sonic X" clothing period. These are small, and meant only for little kids. (as you know this was abandoned for the most-part later) The matching shorts also all have something Sonic on them, usually an embroidered 'patch' of Sonic, or the Sonic X logo. The first shirt has Eggman & Knuckles on it if you look closely. Sets like this were mostly available in JC Penny and Kohls department stores in the USA during their somewhat limited release.
