Fruit of the LoomWomen's Micro Waffle Thermal Set Pajama

They are comfy and the fabric is soft and seems relatively durable. However, they are a bit short for me in the waist. I'm 5 ft 9 in and wear a size 8 dress size (US sizes). I ordered the Medium because I'm usually a medium in shirts/trousers. I needed to wear these as pajamas, and I should have ordered a Large. If you want to wear them under clothes and you have very slender arms, then you can order your regular size... otherwise I recommend sizing up.
