Whether you are young or old, who doesn't love the magic Jim Henson's puppet wizards have been putting out on Sesame Street for the past 42 years? Nowadays you probably already know how to read, write, count and eat cookies but that doesn't mean you still can't rock these Sesame Street shirts and costume dresses with pride. Besides, the children of today need to know that even adults can appreciate how awesome Big Bird is or that The Count is one of the coolest dudes who will ever teach you numbers. He certainly beats what passes for vampires these days. Above all else, with these shirts you can give Cookie Monster the support he deserves. Without it, he never would have gotten onto Saturday Night Live.
