A fresh pair of pajamas is one of the great pleasures of life. If he can afford only one luxury, a man should consider choosing eight or more pair of linen or cotton poplin pajamas so he can don a clean pair each night of the week.
There are silk pajamas of course, but silk wears warm and is not as easy to care for. Reserve it for dressing gowns where odd spots of orange marmalade can be removed with a stain removal product (New York's Madame Paulette offers a good but somewhat pricey one, much like that firm's services generally).
I was once of the opinion that pajamas should be made to measure but I'm no longer so dogmatic. If a man fits relatively well into one of the ready to wear sizes, who is to know? Even the the rest of his household is likely to be too sleepy to notice.
Other than cleanliness, all that's important is that the things are neatly mended, colored conservatively so as not to frighten small children and that the waist elastic does not require constant attention to prevent it from losing its grip. Even ironing is optional.
Wear fresh pajamas.
