If you are near the British Heart Foundation Charity shop in Shandwick Place there is a really nice looking shiny black PVC 3/4 length 'Parka' style coat size 8 on the first rail as you go in on the right.
It isn't my size and as I was unfortunately with a works colleague at the time I couldn't check it out properly

but it did look lovely and crinkly and as I won't be back in the area for a few weeks

I thought I'd give one of you lucky people a chance to go and look see
