In the medical profession, they need to dress up in a way to identify them from other professions. The web site of Blueskyscrubs.com http://www.blueskyscrubs.com/categories/Scrubs/Scrubs-for-Women/Original-Scrubs/ has an array of different designs and colors of uniforms for those in the medical profession. The uniforms are very unique compared to those that you would ordinarily find in stores that sell them like uniforms for nurses. Just viewing the set of uniforms online immediately shows the apparels to be really distinct from ordinary scrubs.
Hospitals and clinics have preferences for color schemes especially for their nursing staff. Often, they would also assign color scheme or code for nurses in different departments. This is one way for colleagues and patients to know what department they belong to. It makes for a very convenient way for anyone to identify them in cases where their services are needed. Hospitals without color coded uniforms for nurses have only their department assignment inscribed on their nameplates.

Uniforms for nursing have become a fashion statement to some and a pride to wear them outside. It serves as a badge for their profession that often helps in emergency cases. Uniforms people wear makes a clear distinction and helps very much in identifying those from different professions.
