Perhaps try Next Hypercurve, they are high waisted ones so don’t constantly fall down and don’t need a belt. I hate belts too and because I’m a pear shape I need them bigger for my bum and legs than my waist. High waisted ones are a good option.
I would recommend new look jeans. I love their mom jeans but their skinny jeans fit really nice too. They are excellent value for money as well, I’ve still got pairs that are years old and they still look new.
You’ve got similar ratios to me - I actually got a pair from newlook it’s a range called “waist enhance” and they fit really well over the bum/legs and don’t gape! They’re not expensive either so worth a try! I’ve also found ASOS farleigh jeans and topshop Jamie jeans ok.
I really like H&M jeans they always fit me very well. The range that cost around £25 are great, I'm always awkward with jeans but they actually fit so well in my usual size.
