MARY-KATE & ASHLEY OLSEN

These two definitely have their red-carpet M.O. down: all black, a close stance and a whole lotta 'tude. They keep it up at the Lexus event in N.Y.C. in fairly nondescript looks, plus funky shoes: cutout booties on M.K. and ankle-tie pumps on Ashley.

Our inner Full House fangirls geek out when the sisters go all "twinsie" on the red carpet. Allover black with a touch of gray (via a tee and a printed scarf), low heels with a pointy toe and wavy center-parted hair is their uniform for the launch of Bik Bok in Oslo.

<em>FULL HOUSE</em>

FULL HOUSE

Watch a clip
In November 2010, 15 years after Full House ended its run, Mary-Kate Olsen and Ashley Olsen proved they were still Daddy's girls when they attended a benefit thrown by TV pop Bob Saget. Afterward, Saget said he was overwhelmed to have them show their support, adding, "The joke I have with them is that I diapered them. They were 3 months old and doing the show, and I also had a baby, and there was a time when I knew how to diaper them really quickly. Of course, I had permission."
