Here are 3 nice shirt selections that seem to only be available at K-Mart stores, in the 'boys / teens' section. The first looks familiar, as it is a modification of a previous design. In this this one though, they replaced Silver with Knuckles, but kept the same 'blue rays' background. Also note the blue collar & cuffs here. The middle is VERY retro, actually to the point of 70s/80s with it's hot pink, yellow & blue color scheme for neo-classic Sonic. It's certainly vibrant, if a bit before his time. The last is a classy modern design, with close-cropping used on Shadow, Knuckles & Sonic's faces to make a sort of portrait & collage. This was also available in white.
