The sixth form that I study at is joining (read being taken over by) a school's trust. They have decided to make the dress code significantly stricter. Currently, it is simply "business wear" but as of September they are making it more specific.
In particular, they are requiring girls to wear blouses/shirts. This would be fine, except that any and all shirts I wear gape open along the line of buttons due to the lack of affordable shirts that suit my body shape. As a result, I would be extremely uncomfortable wearing a shirt, but I don't know how to bring this up with the new headteacher for next year, since she is generally unmoving on issues of dress code. Furthermore, she's not really the one in power, the school trust is, and I have no way to communicate with them that the dress code is unreasonable.
I havent worn shirts for the past two years I've been at the school, and I've been complimented on how smart I look, so it's not an issue of me not meeting the original dress code either. Finally, this issue only affects me as the other two girls in the sixth form are leaving at the end of this academic year.
How do I get my voice heard on the subject by somebody with the power to actually change the dress code?
