It is similar to the White Stuff that I have linked to, but I saw it on a lady today in a plum colour & the collar was different, it kind of had more 'normal' lapels then the WS stuff collar.
I suspect it would definitely be high street, not £££££.
I don't know if it had buttons or not, it could have just been open. I would describe it as a coat, but it could well be described as a 'coatigan' I suppose.
Definitely that boucle material type stuff, came to about mid thigh.
Anyone??
