Apologies if you all already know about this brand - everyone here is about a million times more clued up than me - but I've just bought a couple of things from Scarlett & Jo and I can honestly say that for the first time since being plus size (several years now, thanks to side effects of medication), I've found clothes that actually make me feel good about myself. Up until now I've just felt like a ball of fat in a nice frock. These are flattering, thoughtfully cut, robust fabrics not clingy thin stuff and - best of all - a decent length for wearing chub run busting shorts underneath. Love, love, love.
Favourite thing I've bought is this which is reduced at the moment, but the clearance part of the S&J site has so many bargains too. Of which I am about to partake 
I'm just so happy to have found pretty, flattering clothes which make me feel (almost) as confident at a size 22 as I felt when I was a size 12
