It was 1991—ponytails were worn high, bows were stuck on just about everything, and Mary-Kate and Ashley Olsen were first making a name for themselves by playing Michelle Tanner on Full House. Over the next twenty years, the twins grew up, grew out their bangs, and tried out all kinds of changing beauty looks, both on screen and off. There’s no doubt their style today is sophisticated, but anyone who’s followed them for nearly four decades might find themselves looking back at many unforgettable moments when they matched as twins.

There was the time Mary-Kate dyed her hair brown and broke their classic mirror-image look. Teens everywhere used flat irons to copy the twins’ early-2000s center-parted hair. And who could forget those revealing halter tops, Ashley’s piece-y crown braid, or Mary-Kate’s red lipstick that was perfect for the paparazzi?

As they’ve built their successful quiet luxury fashion empire, known as The Row, the Olsens’ beauty looks have stuck with their tried-and-true formulas. Whether they’re out and about trying to keep a low profile on the East or West Coast, or stepping out for a fashion week show, the duo is almost always sporting honey blonde hair, thick brows, glowing skin, and perfectly balanced nude makeup—their signature style.

Year after year, Mary-Kate and Ashley Olsen have stood out as lasting beauty and fashion icons. To celebrate their 40th birthday, Vogue looks back at their 40 best beauty moments—from (many!) Met Galas to movie premieres, street style shots, and front rows at fashion week. Scroll below.
