I know everything old is new again, but I've been seeing some things that give me pause. I lived through acid-wash jeans the first time, so I'm perplexed by their resurgence. See also: the rattail. The look has been popping up on hipster heads in my neighborhood lately, and I can't say I welcome the return of this hesher hairstyle. Have you spotted it, too? Are you into it, or not so much?
