There's a new style of tank circulating among the sartorial set, and no it isn't the classic ribbed iteration we're used to seeing. If you scroll through Instagram often, you've probably noticed the cool, '80s-inspired padded-shoulder muscle tank tops all over. Often made from cotton, they have a sculpted look yet a languid flair. Wear yours with everything from leather shorts to wool trousers come fall. Shop these must-have muscle tees before they sell out, again.
