Her perfect pixie cut, those metallic stilettos, the spaceman-printed two piece… the "Swish Swish" singer undoubtedly turned heads at the Chanel runway show, and for all the right reasons.

New obsession alert! It's always risky to go bold with vibrant eyeshadow shades, but after seeing the actress sport this trend, we now know it's possible to pull off. Collins left the eyeliner at home, using only mascara on her lashes and lavender shadow over her lids to create a refreshing winged look. Her light pink lip gloss topped it off perfectly.

New month, new 'do! Moments before the Christian Dior runway show, the model debuted her bleach blond tresses on the red carpet, complete with a dash of bronzer, light eye makeup and a striking red lip, seemingly channeling her inner Gwen Stefani.

All eyes were on the model's glistening hairstyle as she strutted her stuff on the Maison Margiela runway. Although she's previously claimed she'd never go full-on blonde, we gotta admit it -- she looks good as a golden goddess.


Zendaya's summer glow shines day and night.

Leave it to Z to slay two completely different beauty looks less than 24 hours apart! The fashionista rocked a DIY top knot and minimal makeup for Viktor and Wolf's fashion show, giving off that gorgeous bronzed glow we all aim for during the summer. She rocked a more dramatic take on the beauty look for the Ralph & Russo show, sporting slicked back, wet hair and a fierce smokey eye.
