Clothing has come a long way since it was first invented. Clothing used to be so constricting in the sense that you can easily identify a stereotype by the threads he has on. Uniforms are just uniforms, very much like badges of honour, one only wears what is duly his. Nowadays, garbs bleed through professions and break social norms. One does not need to spend ten years in medical school to wear a pristine white coat and hospital scrub uniform.
Others may take this transition literally, and there might be some actuality to it but most of the clothing produced by this development in evolution are custom-made, although there are people like http://www.blueskyscrubs.com/categories/Scrubs/Scrubs-for-Women/Original-Scrubs/ who make it ready-to-wear for the commercial masses. They are available both for professionals who need them for its real purpose and to fashionistas as well, without compromising quality and accuracy.
