Though the model Julia van Os channeled the quintessential Libra for W’s spring horoscope fashion story—“some glamorous girl in a pink dress, Princess of Monaco, doing her makeup,” she said on the set of the shoot—van Os herself usually opts for a more understated brand of beauty. (But, in classic Libra fashion, she’s also not opposed to doing it up from time to time. It’s all about balance, after all.)

In the nearly three years since her breakout Fall 2015 season, van Os's ability to disappear into various looks has earned her a diverse array of credits. She has appeared in campaigns for the likes of Calvin Klein and Alexander McQueen and walked in shows for brands as varied as Chanel, Kenzo, Balmain (multiple times over, because creative director Olivier Rousteing likes to keep his favorite models close), and Dolce & Gabbana. Here, van Os dispenses her beauty tips, like how she combats jet lag and why, despite what you’ve been told, you should probably be touching your face—as well as her unexpected, though not unwelcome, doppelgänger.

Your look in three words:
Simple, natural, healthy.

Medicine cabinet snapshot:
Iron, vitamins C, B12, and D3, echinacea, melatonin (for never-ending jet lag).

Best advice from a facialist:
Don’t forget to moisturize your neck.
