Sesame Street may be nearing 40, but the show clearly hasn’t gone out of style.

The PBS program has already played host to a long list of actors, musicians and even First Ladies. Now the famous address is serving as a temporary runway for some of fashion’s latest designs.

For the September 2009 edition of Harper’s Bazaar, a number of designers showcase their creations with help from a few of the street’s most colorful characters. In addition to Vera Wang, Oscar de la Renta (seen after the jump), Carolina Herrera, Diane von Furstenberg and Derek Lam join the fun.
