Trousers are to be kept in a clean and well pressed condition at all times. Creases are to run down the front and back of each trouser leg. A good way to get better creases is to put a little bit of dry soap along the creases on the inside of the trouser leg. When you iron the trousers it acts like glue and makes the creases sharper. The aim is to get sharp crease all along the front and back of the trousers.
