Well my update is that all the coats have been terrible! John Lewis somehow nothing like the pic in my OP, like a big baggy green sack, nothing special.
My last hope is the Plant hunter, but looking at reviews I may have ordered the wrong size 
I also tried on a Tresspass celebrity in a store - was a good shape and I think could work if Plant Hunter doesn’t, although wasn’t sure of the colour I tried (green) on me.
Overall I might be getting ready to dump the Parka idea completely! Stylish Parka may be an oxymoron after all, at least for me. I’m short and curvy and they don’t seem to do anything for me. Maybe time for a tailored wool coat instead...
