While for some the image of a bouffant hairstyle might conjure up a mile-high mess stiff with hairspray, '60s bombshell Brigitte Bardot made her half-up bouffant the sexiest look you could ever imagine. All Things Hair calls this half-up, half-down style "timeless," noting it's a favorite look of sadcore crooner Lana del Rey. 

Byrdie agrees the bouffant look is long overdue for a comeback, noting that this simple yet stylish look is surprisingly easy to put together. Pair it with Brigitte's signature cat-eye liner and some go-go boots for a look that's hotter than an atom bomb, baby!
