I like to use professional people wearing formal scrub. They look so smart into scrub tops and bottoms. When I was admitted to hospital that time, I can see those nurses and doctors wearing different scrubs. Some how when you see them, you will feel like having some security. As you know, hospital always give us one kind strange of scaring feeling. But when I see them wearing formal scrubs and around me, I will feel I am secure here. LOL….strange feeling right?
