There hasn’t been this much hoopla over a hair accessory since Princesses Beatrice and Eugenie wore those wacky fascinators to the royal wedding two years ago.

Supermodel Karlie Kloss is used to making splashes on red carpets. The gazelle-like stunner always looks so sophisticated and poised. That’s why the beauty world was collectively surprised when she stepped out at a gala wearing…a black, gym-inspired headband. Maybe she was having a bad hair day, maybe she wanted the focus to be on her lithe features and amazing cheekbones, but this look seemed a bit…off.

Cut to one week later, when Amy Adams (A-lister, fashion icon and usual red carpet winner) wore a similar headband to the London Man of Steel premiere. Is this trend here to stay? Amy’s thinner version appeared to be more like a ribbon, rather than a workout accessory. It admittedly added a certain charm to her Valentino knee-length dress.

The casual look juxtaposed with a formal outfit isn’t for everyone, but it looks like it’s a trend that may be catching on…at least for a while. Are you on board with the headband at night?
