Right, I initially thought it was Cath Kidston because it was that lovely mid blue and it also had white dots all over it (but I've now seen her dots were much smaller than CK). It was in that material that some of the Cath Kidston bags are in, the stuff you could probably just wipe over, like the vinyl you used to cover tables with in the old days!
The style was like a fitted mac, that came mid thigh. It looked like it had a hood that was detachable. The pockets at the front (side) were slanted. So although it looked like it would be a CK, there were differences in the ones I've seen online to tell me it wasn't.
I want it!!
