Slim fitting school blouses

[Digitaldelight]

Can anyone help? My 14yo DD is almost 5’9 but super slim and can’t find white blouses that are fitted enough for her. Eg M&S slim fit is wide and boxy on her and it’s difficult to tuck into skirt or trousers. Any suggestions? In the hope that she won’t grow any more, I’m prepared to pay more for non “school” ones if they fit well and will now last. TIA

We get the Winterbottoms ones and find them very good quality:

I should have said - they’re a genuinely slim cut and in my experience far preferable to M&S.
