plain cotton jersey loose tapered trousers or joggers?

[OneStepMoreFun]

I can't find any anywhere. I don't want cuffs or cropped or tight, but not harem style either. Just full length tapered soft trousers or joggers, ideally in black, navy or charcoal. Winter weight would be great but not essential.
I've looked on Asos, M&S, Sports Direct, Decathlon etc. Does anyone know where might sell them?

Next do them, but they are viscose not cotton. They don't have a cuff and do them in black and navy.

Uniqlo lounge trousers

Daft I looked at Next but couldn't find any that weren't skinnies or with cuffs. I'll have another look. Don't know how I missed them.
Uniqlo is a good idea.

Pea Those Uniqlo ones are perfect. Don't have them in my size online, but I'll go into town and look. Thank you. That's exactly the sort I had in mind.
