When we're feeling bored with the state of our hair, many of us turn to a new cut or color. But for commitment-phobes who don't want to take the plunge, the next best thing is a hair accessory to jazz things up temporarily. Celebrities, pop-culture icons and royals throughout history have been known for wearing them, and fashion is taking a cue from them for fall: Expect to see an abundance of hats, headbands and berets. Hailey Baldwin, for example, turned heads last night in Milan at the amfAR gala. Hairstylist Jennifer Yepez slicked back Hailey's long blonde tresses with a thick black band, bringing out the model's eyes and highlighted cheekbones. It's a modern, grown-up take on a look we wore in middle school, and we're loving it. See Hailey's spin on the classic below, as well as how other It girls are styling the trend.
