Jeans help needed please

[Itwontletmenamechange]

I need some new jeans as my current collection is either too big/too small or they need binned

I have spent the past few years in skinnies but I have quite chunky thighs and I'm not sure they're quite right. Have tried straight but feel they make my legs look wider.

Am size 12 (10 in vanity sizing eg gap/next) would like darker denim and something that I can wear with biker/chunky boots in winter but converse/flats in summer which is where I struggle as straight legs don't work with boots but converse look daft with skinnies (on me)

Low budget (usual trying to lose said thunder thighs excuse) so would go to£30

Thanks
