Loungewear Set Sets are sold as is. No substitutions can be made. Our Soft Lounge Top is made from the same patented non-pilling micro modal fabric as our Soft Underwear. It's so silky and luxurious, it will feel like you’re not wearing anything at all. We took the same patented non-pilling micro modal fabric as our Soft Underwear and crafted an airy lounge pant that you'll forget all about as soon as you slip them on. That is until you have to pay the delivery guy, which is exactly why we added pockets. Fabric: 90% Non-Pilling Micro Modal, 10% Spandex Premium Fabric Silky soft, featherlight, and non-pilling.
