The word "scrubs" has been given a negative connotation when used to reference a person. Yet the concept of surgical scrub clothing is far from being "scrubby" -- the professionally designed wear for doctors, nurses and other health care professionals has gone main stream outside of the medical facility because it's comfortable.
The days of the green scrub pants may still exist in some medical settings, but for the most part, in the outside world of consumer wear, there are bright colors and a variety of patterns.
Beyond comfort there is cost, cheap scrubs can be found, at times even with holiday themes for those of you looking for a bit of pizazz with your scrub wear. My personal favorite has bats on it. I love October since it's the one month I can wear them out of the house without getting strange looks.
