Where can I find stretch jeans in the UK, I am a size 12 with a big .?

I have a big and I can fit comfortably into stretch jeans. Where can I get these from. PLEASE DONT TELL ME TO GO ONLINE, I need to go directly into a store and try them on for fit. They dont have to be stretch as long as I can find a place that caters for women with curves. These damn jean companys only seem to cater for narrow and flat behind women.... no offence. HELP PLEASE
