If you've ever tried to wear your hair to one side all night, you know getting it to stay that way can put a serious crick in your neck. But if you look at what's actually happening on the side of Cara Delevingne's hair here, you'll see that she's getting a little help from some hairpins.
Several of them, actually. They're all lined up to keep her hair tucked around the curve of her skull. And they're multi-taskers-they're useful and they add a bit of an edge to an otherwise classic style. Sweet.
I think I just made your holiday party season a little easier on your neck, no?
