This is called the "Confetti Long Sleeve Tee". It has a rather retro-style background rectangle full of wiggle lines & dots. It uses the seldom-seen 'thumbs backward' Japanese Sonic classic stock art. His name is spelled out in large Japanese letters at the bottom, but then under it it has "Sonic the Hedgehog". The tee is otherwise all white. Having the Sonic element as white & the background a bright blue is a nice touch that makes it different. All the elements here are really combining nicely to give the shirt a classy & uniqe look. This is a winter 2021 item, but where?
