I bought a top by Whistles (previous season version of this in a charity shop and it's amazing! The fabric skims over my mum-tum (7lbs still to lose) and it makes me look skinny (am size 12). Plus it doesn't need ironing, which I adore.
I am putting this miracle down to the "Pima cotton and modal" fabric mix. I've looked for other clothes with this mix and found a few on net-a-porter. So is this some "designer" clothes magic fabric combination, not intended for mere mortals?
