Of course you need something green to wear today, or even tomorrow, and you can’t get any greener than the Green Lantern.
Show your support for intergalactic forces of peace with this Green Lantern Splatter Symbol T-shirt. This is a rendition of Hal Jordan’s original symbol (in an edgy update) . Get it from Entertainment Earth for one of the lowest prices online. You can always wear it next year on St. Paddy’s Day, though you may still get pinched, just because it’s cool.
