Meet the Nina Pajama Set. Does that perfectly ruffled lettuce edge immediately make you think of slumber parties with all of your besties eating Pizza Bagels with Clueless on the big screen and the fresh scent of face masks and nail polish remover? No? Just me? Either way, Nina is perfect. Nina is a short sleeve t-shirt and shorts set made from the softest, stretchiest organic cotton interlock fabric – the same fabric we use in our baby products, so you too can sleep like a baby.
