Simon Balle uniform (Hertford SG13)

Just wondering if anyone has some boys'/girls school uniforms for Year 10+? Our daughter likes to wear trousers; she sees them as more comfortable, and she likes ties! For sport classes, she is fine with skorts or trousers. She is 173cm tall and slim-built. She is starting Year 10 after the summer holidays and has nothing (the colour will be different)
