Do these trousers exist?

[Pinkkahori]

It's very warm here and once I got home for the day I changed into some cropped pj bottoms I have. They are so comfortable. Cotton t-shirt type fabric and straight leg with only a thin elastic in the waist.
I have similar in a full length leg and think they look quite flattering on me.
I am short and apple shaped and I find it difficult to get trousers. I've searched online but can't find anything. I have Next harems which are ok ish but not that flattering on and also some yoga style trousers but the fold over waist is too bulky and warm at the moment.

What I am looking for:
light cotton with maybe some stretch
straight leg - not harems or very wide leg
plain dark colours - navy or black
full or cropped leg.

Has anyone any suggestions?
If my pjs weren't so old and worn I would consider dying them.

Uniqlo do lots of jersey/linen/relaxed fit trousers

I got some stretchy cotton trousers from H&M today. Mine are patterned, but they also come in black. They look a bit baggy round the crotch in the photos, but they weren't when I tried them on though I do have a rather substantial bottom

Thanks for the replies.

I've never bought anything from Uniqlo. Looks like they have some possibilities.

I like the H&M ones but I'd have to see them in person - don't think the low crotch look is for me.

Had a quick look at M&S but didn't find anything I like.
Thanks
