The Trees Are Cool t-shirt, via Cafe Press
SHIRTS WITH A SUNNY OUTLOOK: If you're thinking of joining an Earth Day celebration -- either via the California State Parks Foundation or at the Venice Eco-Fest or just in your own yard -- and you haven't got a thing to wear, Cafe Press has rounded up a whole clutch of Earth Day-themed tees. But of course, so many Earth Day outings involve elbow grease and plenty of clean-up, so going a bit dressed-down for the day is not a bad idea. Then, save your planet-nice tee for a fancier occasion, to better spread the word. TEE TIME: The Trees Are Cool tee is $24, at Cafe Press.
