This week marked the return of "Mad Men," but if you think "Zou Bisou Bisou"-mania overshadowed the show's always fabulous fashion, think again -- that little French Canadian coquette Megan made our best dressed list, too.
We had some other favorite TV fashions from this decade, too, like a sexy man from a show you're probably not watching (but should be), an Original vampire and a "Fashion Star" mentor. But other TV characters weren't as lucky. (We're looking at you, "GCB," "New Girl" and "The Real Housewives of Orange County.")
