We call this the one-shouldered wonder. This asymmetrical one-piece bather features a single adjustable strap that lets you tie the bow up as tight or as loose as you please, plus another little bow just for show at the hip. Cut in our luxe supreme Italian Lycra, it's sexy but not skimpy (personally how we like our beachwear), as perfect for the pool at Il Pellicano as it is under a pair of linen shorts for perusing a Caravaggio in Rome.
