I'm a size 18-20 and have spent the last few years in black leggings and tops that cover my bum!
I have found the most amazing jeans, they're called "Kate" and are from Peacocks.
I have them in 5 colours, 3 denim variations, 1 white, 1 black, £14 each an absolute bargain.
I still haven't had the guts to wear the white
They are the most flattering ones I've ever had and I'm pretty hard on myself, no buttons or zips and they're high waisted which I love.
Thought I would share
