Being that I am what I call a "professional medical patient," I have seen all kinds of scrubs. I've seen plain and patterned, ones that fit well, and ones that fit not so well. I really like some of the printed ones with designs, except that they always seem a bit childish.
Well, at http://www.blueskyscrubs.com/ you can get any color of scrubs you want. They have very colorful, fun, patterned scrub hats to make up for the unitary look of the scrubs them selves. They even sell earrings, bracelets, and really cool lanyards. Check it out!
