Don't Miss:

Rose Byrne’s long bob and chin-skimming crops continue to give us hair envy, and our readers agree! Over 13,000 of you tried on her range of styles in our Hollywood Makeover Tool this week. So, what’s her secret? “My secret is Harry Josh! He’s been my hairdresser for years, and is a very dear friend of mine,” Byrne told us at the grand reopening of Sephora’s Times Square location in New York City. “My hair is actually quite difficult—it’s thick and coarse, and somehow he tames it.” Luckily, you don’t need to book an appointment with the star’s hairstylist to see yourself in her signature looks. Simply head over to our Hollywood Makeover Tool and upload your picture to sample Byrne’s hairstyles. You can even print out a version for your most-trusted hairstylist if you’re considering making the cut as well. Click the link below to start!

The ladies of Downton Abbey might get a lot of attention for the costumes—Lady Sybil dominates the sartorial scene, even if she’s wearing Uggs under her hoopskirts—but the gentlemen deserve a nod too! Brendan Coyle, who plays the kindhearted and constantly mistreated head servant Mr. Bates, told InStyle.com he loves the suits he gets to wear on set. “I’m a big fan of them,” Coyle said. “You feel different when you put a suit on. I think of my two grandfathers. They were steel workers, but in the evening they would scrub up and put on a tweed jacket. They’d be very dapper men on the weekend. It’s important to feel good about yourself.” And even though he’s not wearing corsets like Michelle Dockery’s Lady Mary Crawley, there’s an element of strictness to his wardrobe as well. “There’s a rigidity to his costumes—the buttoned-up coats, the starched collars—it commands you to be upright and erect,” Coyle said. “The attention to detail is amazing.” See Mr. Bates and all his dapper fellow stars in action when Downton returns to PBS tomorrow, January 6, at 9/8c.
