As the healthcare industry has developed, so has the way people dress in it. Medical uniforms are now available in a variety of designs and colours. Among the various colours available are green, blue, navy blue, maroon, grey, black, walnut, lilac, pink, and wine. Scrubs for physicians and nurses are now multi-functional, with several pockets for keeping all of the necessary and useful items for the work, such as documents, gauze, stethoscopes, and injections.
