I'm 72 years old, 65 1/2 inches tall, and weigh 110 lbs. I took a chance on size 16 in the Nordic Dreams pajamas set to wear as long johns on not-too-freezing days. They fit like a women's small--and are perfectly soft and comfy. They also launder well on cold + tumble dry, but you could easily hang to dry with zero problem. The vikings are an added hilarity bonus for an old hooligan like me. Don't let toddlers have all the fun!
