Pink dressing gown Size 8? (North Acton)

From my neighbour.
A pretty pink dressing gown.
No indication of size. But the sleeves are shorter than a dressing gown that's size M, so I reckon it's size S/8.

There's a small black stain at the front and a couple of stains on the inside only.

The colour is more like on the first photo.
