Ok, I am not exactly slim....I shop in Evans if you know what I mean. I have never been able to find jeans that fit really well even when I was smaller.
BUT I went into a big Evans and found pear shaped jeans....I never knew they existed and they are a revelation!!
I no longer have jeans that always gape at the back showing off my pants which I have to hitch up with uncomfortable belts. They even had them in a lovely retro bootcut which I adore so feeling rather happy with them right now.
