Skulls aren’t just for bikers and pirates anymore. If you thought skulls and crossbones were morbid, menacing, or just plain silly, it’s time to bone up on your fashion sense. Anyone with a pulse has to have noticed the proliferation of skeleton craniums on everything from aprons ($30) and maternity skirts ($70) to this pink skull T-shirt dress ($21) for toddlers. Skulls are about as hip as you can get, as evidenced by these Christian Audigier Charmed Skull men’s board shorts in black ($128) or these Juicy Couture men’s skull-print board shorts ($78). Girls like empty heads, too. Check out this black and white sundress (on sale for $37) or this pink bandanna halter dress ($59; pictured). Both would look mordantly good with a pair of flip skull sandals ($23). For boys, a pair of Vans Ferris skulls skate shoes ($45) might revive a fading fashion reputation. Skulls can even be cute, as on this pink skull denim handbag ($29) and this sterling silver skull and crossbones bracelet ($68). The trend is more than a bit of skullduggery. It appears to be serious business.
