WW1 officers trousers?

[inka]

Hi guys.
Could anyone help me identify these trousers? Havent found any stamps in them.

They look very similar to WWII DR trousers, do they have any sign of a removed label on the exterior around the back of them? I don't recognise the buttons so I might be completely wrong on these.

DR? Cant see traces of any labels no..

Despatch rider. As I posted, perhaps totally left of field then. If officers private purchase riding breeches then they are likely to be impossible to date, have you tried researching the button makers?

Thanks Anon. I`ll have a look into the button world to see if I can find a clue
