On Trend: Cannes International Film Festival

At a press event for Kung Fu Panda 2, the mom of 6 sticks to her staple look of loose waves and heavily-lined eyes.

Howard tames her scarlet mane (just think of that humid Mediterranean air!) into a braided, nape-of-neck knot at the premiere of her new film, Restless.

Our favorite German actress (and trend-setter) pairs a messy side braid with immaculate makeup. We're loving how the loose tendrils dress down her black-tie look.

Perhaps inspired by the Fall 2011 Giorgio Armani show, Lady Gaga doubles up on eyeliner—and hair color shades—for her Cannes performance.

So long, Sucker Punch. The Sleeping Beauty star amps up her ingenue look with a silver-y smoky eye.

The Restless star pins back her newly-cropped cut into a modern flat chingon for the premiere of her new Gus Van Sant flick.

The stunning French actress (she was amazing in Inglorious Basterds!) opts for an icy-pink blush to match her lighter hair at the Opening Ceremony for the film fest.

In just one of her many head-turning Cannes looks (and with a nod to the festival's location), McAdams vamps up a neutral-toned pantsuit with a Bardot-esque coif and pink lipstick.

Swinton ditches her minimal style in favor of fuschia lips and rosy cheeks. We love how this brighter makeup palette softens her look.

We imagine these two actresses bonded over more than their matching looks of dewy skin, coral lips, and glossy strands while attending a Calvin Klein party for the brand's Euphoria perfume at the famous Martinez Hotel.

At the The Kid with a Bike premiere, this Belgian actress sculpts her curls into face-framing waves, a la the Spring 2011 Prada runway show.

Stefani might be in her fifth decade—she's 41—but her icy blonde curls, electric lips, and fair skin (SPF pays off!) help her dominate the red carpet at a movie premiere.

The Czech model (and new mom) accents her long ponytail with a braided, modern twist. Winged eyeliner is the only makeup she needs to dress up her sun-kissed glow.

At the The Tree of Life premiere, the Chinese actress rocks matte lips, full lashes, and flawless skin. We love how her Heidi-seque braids create a seamless halo around her head.
