From the info tab:
Scrubs are the shirts and trousers or gowns worn by nurses, surgeons, and other operating room personnel when “scrubbing in” for surgery. They are designed to be simple with minimal places for dirt to hide, easy to launder, and cheap to replace if damaged or stained irreparably. The wearing of scrubs has been extended outside of surgery in many hospitals.
