These trousers have a full width elastic waistband plus a drawstring -- MATERIAL - made from excellent quality - Bright White - Pre-Shrunk - Easy care - 8 oz Polycotton fabric that will stay good looking and last you a very long time -- IMPORTANT SIZES - Check your child's actual height by standing them against a wall and then measure down to the ground from level with the top of your head - NOTE - that all of our Trousers are made to fit a large person at the maximum height shown so if the child is slim the size below MAY be good for them - ALSO - we do NOT recommend buying a larger size for your child to grow into as this will swamp them so they are not be able to move properly.
