Hi! I’m Jeannie and I’m 13 years old. I go to school in our town.
At school we always wear a uniform. Girls wear white shirts, blue skirts and red sweaters
with the school emblem. Boys wear white shirts with blue ties and blue trousers. Their sweaters are
red, too. All of our shoes are black. We don’t like our school uniform. After school my first thing to
do is putting off my uniform. I hate skirts and dresses! I like wearing casual clothes. I often go
skateboarding, so my favourite pieces of clothes are very comfortable. I like trousers, jeans, shorts,
T-shirts, jackets, trainers and I have lots of baseball caps. I never wear dresses and skirts when I’m
not at school. Mum says that I should wear girlish clothes, but they are uncomfortable for me!
