I would definitely take a look at all the current Cos trousers, @pomeglamate. It’s absolutely the go to place for anyone wanting something approaching MH cut and quality.
(And you’re right to acknowledge that you don’t find decent tailored trousers in good fabric for less than Cos prices.)
BTW, it’s worthwhile signing up to the MH mailing list - that way you’ll have advance warning of sample sales, and regular sales (where MHL, as opposed to main line clothes, take on High St prices). Also try pre-owned sources: Vestiaire generally has a good supply of MH. If genuine and in good condition it isn’t cheap, but it will be more affordable than straight out of the shop.
Oh, another brilliant place for well cut trousers - less expensive than MH, more expensive than Cos, is:
Studio Nicholson.
Excellent quality, cool, innovative cuts and interesting fabrics.
You could also look at
Rohe
Aime London
Acne Studios (just the best cutting and fabrics)
& Other Stories
is in a period of wonderful design - but you can’t expect the same level of quality there.
