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.
