Where can I get full length, straight legged, high waist trousers?

[CeliaFate]

I've got a muffin top I need to hide with a high waist. All the straight leg trousers I've found are low rise.
I have New Look skinny jeans that are fab, but can't find trousers.
Any help please?
Budget :Under £75.
Size : 12
I don't want 7/8, cropped or 3/4 trousers, just full length ones.
Not an impossible dream, surely? But I'm buggered if I can find them!

I got a pair if LKBennett trousers just like your description for £30 on ebay recently. They were like new and so versatile!

I got M&S straight leg, with stretch for £25. I think they may be advertised as bootcut, but they are quite straight at the bottom. Am wearing them so cant see the code. They do navy, black and maybe beige?
