Rashida Jones's Changing Looks

At her 25th birthday party, the Boston Public star played up her deep brown eyes with bright lilac shadow.

Jones hit the Little Black Book premiere with a tousled updo and sideswept bangs.

She joined her The Office castmates at the Emmys sporting her favorite lip hue. "A red matte lipstick adds instant glamour," she has told InStyle. "Nars Velvet Matte Lip Pencil in Cruella is a true scarlet."

Jones let her waves loose for the I Love You Man premiere.

Her ombre bob was understated by design. "We've been keeping her hair very simple lately," hairstylist, Chris McMillan told InStyle.com. "The bottom is one length because we're letting her layers grow out." Shaping long bangs that sweep across the forehead give the classic cut a modern twist.

For the Costume Institute Gala, the Parks and Recreation star topped her buoyant curls with a diamond headband from Fred Leighton featuring a '40s-era winged brooch.

She switched up her look for an NBC party with trendy bright pink lipstick.

For the Women in Hollywood Party, Jones paired a fishtail braid with winged eyeliner.
