Gap teeth, grillz, and even fangs have all had their fashion moment. Now, everyone’s favorite tween accoutrement, braces, has stepped into the spotlight. Model Kitty Hayes sports them on one of the covers of CR Fashion Book‘s latest issue. (She made it, despite the fact that, she tells the magazine, she once showed up to a casting with spinach in her braces.) Also repping the metal-mouthed look: model Charlie James, who won our hearts with his headbanging at Opening Ceremony, and members of Hood by Air’s model crew this season. One thing that’s probably never going to be cool, though: full-on headgear.
