Thank you for viewing. I've worn this a few times and stored it folded in a chest of drawers. There are quite a few fold wrinkles. It's pajamas with a smooth, light feel. The top has slits on both sides. The pants have elastic in the back. There are no drawstrings for size adjustment. Please check the images.
