A lot of schools have a choice of uniform so that children can wear what they feel most comfortable in. For example, in Australia, which is a very hot country, schools often have a summer uniform of clothes that are more comfortable in the hot weather [9]. This means that in summer, children might be allowed to wear shorts instead of trousers and short-sleeved instead of long-sleeved shirts.  If children were allowed to choose their own clothes to wear to school, instead of a uniform, they might choose impractical clothes themselves, like baggy tee shirts or long skirts, or jeans with chains hanging from them. To make sure that children are all wearing sensible clothes in which they will be able to take part in all their school activities, there needs to be one uniform that all children at the school wear.
