Gossip Girl's Chace Crawford may star in one of TV's most stylish shows, but does he have what it takes to dish fashion advice? UK magazine Grazia put the actor to the test as this week's guest fashion editor, and Crawford was tasked with picking a hot accessory each day (a Mulberry bib necklace and Victoria Beckham aviators have made the cut so far). He also weighed in on summer's new fragrances, deeming Stella McCartney's floral-scented Sheer "very sophisticated." The actor even tackled a fashion quiz, where he rightly guessed what trend Gossip Girl character Blair Waldorf popularized. "Headbands! I definitely know that one," he said. (Relive Blair's best headbands here!) Our take on his skills? Watch out Leighton and Blake, there's a new fashion expert in town.
