I want to get one for my parents when they come to visit as I know they will appreciate it. There is only room for one in the wardrobe, so needs to be unisex. It doesn't need to be warm and fluffy (in fact it would be better not as those ones take up so much space), just a long, light cover-up so they can go to the bathroom in their nightclothes without feeling uncomfortable about meeting DH (they are quite elderly and old-school!)
Any ideas? I was wondering about a thin cotton navy one or something like that, but I can't find anything that looks good and would be equally nice for both of them.
