I'm retired from the healthcare business, so I don't have to wear scrubs anymore.  However, I wanted some to wear at home, and running errands.  Since I normally wear Large or X-Large, depending on the brand, I ordered large.  Could have ordered a medium, but it feels so good to have a large size feel a little loose.  These pants are everything the manufacturer description says.  Comfortable, tough, don't wrinkle, ok to put in washer and dryer (I dry them on delicate).  I'll definitely order another pair when I get paid.
