You know those beautiful, dark brows Cara Delevingne is famous for? Yeah, well she ditched 'em all in the name of fashion.

The supermodel — who's also best known for yachting with her A-list BFFs and wearing, well, nada — looked unrecognizable when she walked the Givenchy spring 2015 runway show during Paris Fashion Week on Sunday.

Thankfully it wasn't permanent (though home girl still looks flawless). Riccardo Tisci had the models, including Kendall (formerly known as Kendall Jenner), bleach their eyebrows for the runway gig.
