THE LOOK: Subtle cat-flick eyeliner and Dutch braids done the French way. Redken Global Creative Director Guido Palau created soft plaits along the hairline. Models with textured hair had their hair braided back into individual styles.

THE LOOK: Dries Van Noten teamed up with Christian Lacroix for a collection and the result is a stunning mix of jewel tones and floral prints. Feather accents were added to the hair by Sam McKnight, and Peter Philips tied in the show's color palette by painting stripes of gold, black, and white across the model's eyes. Some even wore gold metallic lips. 

THE LOOK: Super sleek ponytails and deep side parts. Redken Creative Director Guido Palau used strong-hold hairspray to hold the look in place. The model's faces were left bare except for a touch of lip balm.

THE LOOK: Paco Rabanne was one of the many runways to feature deep side parts and air-dried hair. 

THE LOOK: While the model's faces were left bare, except for a strong brow and some mascara, Pat McGrath gave some of them bleached brows and swipes of statement-making turquoise eyeshadow. 

THE LOOK: Saint Laurent's hair and makeup look is one you can actually do yourself. The hair was parted to the side and tucked behind the ears, while make was kept minimal, save for some highlighter. 

THE LOOK: Running with the show's intergalactic theme, mini constellations of glitter were applied to the inner corners of the eyes and bridge of the nose. The hair was parted down the center and tucked behind the ears. 

THE LOOK: Black lips aren't just for fall. Case in point: Courrages' models wore glossy raven lipstick. 

THE LOOK: Celine's beauty look incorporated two '70s-inspired tends: Kohl-rimmed eyes and all lengths of shaggy haircuts. 

THE LOOK: Clumpy lashes, but make it fashion. Makeup artist Vincent Oquendo turned one of your biggest mascara struggles into a fashion week beauty trend. Each x Other's show also featured shags, the style that will replace the bob as 2020's most popular haircut.
