Eyebrows disappeared on the spring 2010 runways. No need to thread, wax, and tweeze them anymore. Just bleach, cover up, or shave 'em off. Lanvin and Jonathan Saunders dyed the ridge hairs yellow, as did Bottega Veneta, which Chanel Iman said she hated because they made her feel like like she was on another planet. The otherworldly look was exactly the aim for Alexander McQueen, however, who applied prosthetics to faces for a runway of model aliens, covering up arches in the process. Givenchy mimicked its browless fall campaign on the catwalk, while a model at Prada looks like she plucked hers off completely. And it's not like this idea is that far-fetched to jump from runway to reality. Karen Elson famously buzzed hers off for a Steven Meisel–shot Italian Vogue cover in 1997, which became a benchmark moment in her career. It's circling back now, perhaps as a beauty interpretation of spring's lingerie trend, only on your face — another way to be revealing and stripped down.
