I have been wearing  Karen Neuburger pajamas, size XL for many years.  I purchased these in the Navy Foulard print for a change from the pastel colors.  I found the size to be consistent and did not find the waistband to be uncomfortable or too tight.  The fit and color are very flattering.  Very comfortable as loungewear as well as for sleeping.  These pajamas are tailored in a blend of 60 percent Cotton and 40 percent Polyester.  The label states that they were made in Cambodia.  The fabric feels a bit thinner than some of my other KN pajamas and I did notice a very slight dye odor upon opening the package.  I'm going to run them through a cold rinse cycle (delicate) before wearing.  Personally, I prefer to hang them to dry but they can be machine dried on a delicate cycle.
