Looking for Nightie with Hood

I'm looking to buy a nightie with a hood for my 87 year old mum who gets cold at night in bed. We got one a few year's back which she loves but could really do with another. I can't find any online that aren't fleece. She doesn't want fleece for sleeping in.

Anyone help with suggestions or seen any in shops around your own town? It can't be an unusual problem so what do people do to keep head warm at night?
