It might be Friday the 13th, but this morning also signifies a Very Important Holiday: today marks the birth of everyone's favorite twins, Mary-Kate and Ashley Olsen! The girls are turning the big 2-8, so obviously we have to celebrate.
And there's really no better way to do so than by taking a trip down Olsen memory lane, starting with their Full House days all the way up to styling lessons we've picked up from The Row and Elizabeth and James. "Gimme Pizza" slowed down? Check. All of the girls' NYLON covers? Duh. Investing in a good pair of overalls inspired by It Takes Two? Of course, it's all here.
So get schooled in Olsen 101 here, then tell us your favorite MK and A moments on Facebook.
