Question

Answer 1

hopefully clothes

Answer 2

All doctors wear blue scrubs.  They will wear white coats too.  

Med students wear scrubs and they also have a white coat, but you can tell from the length of the white coat if they are a student or an M.D.  If the white coat is short, that person is a student.  

My ex had to buy his own scrubs and white coat.  His med school had a "White Coat Ceremony" at the beginning of med school where each student is presented with a white coat.
