Meet the Kelly 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, the Kelly Pajama Set is perfect. The Kelly Pajama Set is a short sleeve t-shirt and pant 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.
