So says Sophie Scott, a school uniform activist who has turned to the Internet to encourage fellow pupils to campaign to be allowed to wear trousers.
Sophie, 14, won her battle at Ricksmansworth school, Hertfordshire. Teachers and governors decided to allow girls to cover up with a change in uniform policy at a meeting last month.
She now exorts others with the message: "There are still many schools where girls cannot wear trousers as part of their uniform. I think this is really unfair as girls get old too.
"You always have to worry when you bend down to tie your shoe laces or when it's windy.
"Also, we constantly have to shave our legs if we wear skirts!
"I'm sick of girls being discriminated against in this way."
In February, Professor Claire Hales challenged the skirt-only uniform policy at Wickham comprehensive, in Gateshead, on behalf of her daughter Jo. Her campaign was backed by the Equal Opportunities Commission.
The potential costs of the case forced the school to settle out of court and its revised dress code allows boys to wear skirts.
