Celebrity Trend: The Undone Updo

Stars are letting loose and giving effortless updos a whole new meaning this season. Undone, intentionally messy effects are replacing the classic half-up styles on the red carpet. The look is flirty and fresh yet still formal enough for a high-glamour fete. Check out celebrities' takes on the trend, then vote for your favorite below

GWEN STEFANI

Gwen gives her topknot extra edge by purposely leaving tendrils out of her bun. The spiky effect complements her fashion-forward wardrobe and power pout.

MOLLY SIMS

Opting for the classic undone updo, Molly allows large face-framing pieces to hang loose in the front. The effect resembles a faux bob-like style.

Olivia sports a messy twisted style in the back, but keeps the front simple with only a few thin tendrils hanging around her ears. The looped updo is effortlessly chic and unique.
