I am looking for slim fit, long fit cargo pants or frankly khaki coloured trousers will do. A bit of stretch would be even better 
Whenever I search I get massive baggy beige things which is so not what I'm looking for. I want something neat to go beneath jumpers. And I am very tall so the mid-rise ones just make me look like I bough too-short trousers.
Perhaps I'm inventing a type of trouser which doesn't exist?
