Nursing scrubs are viewed as a necessity more than anything in most hospitals. Even though they are a necessity, sometimes it can be difficult to find the properly fitting ones out there. It takes a lot of time and effort, and once a person finds exactly what they want, they need to be ordering a lot of them.
This type of clothing is something that really should not seem like it is that big of a deal, but it is a uniform that is worn each and every day. It can be a very difficult process to find exactly the right fit, and that is why so many people are willing to invest once they do.
Go with different color choices if at all possible. Some hospitals are only going to allow certain colors, but variety is always going to be cool.
