Any suggestions??

I’m 14 and very slim with very long and slender legs. I’ve been looking for some jeans that will actually fit me but it’s very very hard to find any. I’m usually a size 6 in women’s clothing or age 14-15 in kids. I have a couple of pairs of jeans now that fitted me a few months ago when I got them but now they’re too short😣! I’ve tried looking for size 6 long but somehow they are wider than the regulars??🤨 All the jeans I’ve tried on in shops are either too short, too big on my waist or sometimes both! The fact that I hate ripped jeans makes it even harder because most jeans on the market have rips in them.

I would greatly appreciate any suggestions on shops that sell jeans that might fit me. ( also I live in the uk so some shops may not be available)
