It's no secret that '90s and '00s fashion is coming back in a big way. Things like chokers, hair barrettes and flare jeans are hitting shelves again, and nostalgia-lovers are all about it. One trend you probably thought you'd never see again? Puka shell necklaces. These chokers, typically synonymous with surfer dudes and frat bros, fell off the face of the earth a few decades ago but have recently been seen on runways and in online shops all over the place. While you probably won't (and probably shouldn't) spring for something like model Gigi Hadid's Tohum take, which goes for $420, how many of these other renditions would you clasp around your neck?
