Uniforms

Went to the school choir concert to see our grand-daughter perform with the rest of her year.
All dressed uniformly in white tops and dark trousers, a very pretty sight, charming singing too, BUT....
what happened to the uniform shoes?
As an aside, lots and lots of photos being taken by all and sundry, no restrictions on photographing school events in Switzerland then.
Off to the UK Saturday, no blips until Thursday, I'm afraid.
