Best pyjamas to take someone in hospital?

[PopcornChewingGum]

My friend has been taken to hospital with severe breathing difficulties. She has no immediate family around so I'm her support system. I'm nipping out to get her some pj's and toiletries. If you have any relevant experience, please can you advise me: what are the best pj's to get ? Nightie? Button up? Warm or cool ?

And the most crucial toiletries ? Obviously toothbrush and toothpaste, face flannel, face wash. Anything else ?

Hospitals can be warm but they can also be absolutely freezing - some have the windows open because of covid.

So maybe a fleecy top or something too?

Button up as breathing difficulties might need access. I always feels cold so I'd want warm pj plus fluffy socks and a fluffy dressing gown/cardigan/fleece.

ear plugs
ear phones
phone charger
eye mask
drinking bottle with sports top
wet wipes incase she is not allowed up to bathroom for medical reasons
easy reading/puzzle book and pen

Depends on what's happening.
If she has a catheter in a nightie is easier.
If she's up and about a bit she might feel pj's are warmer /covered up.
If having difficulty getting arms up button front may be best.
I think I'd ask what's best.

Thank you all dear MNers for your suggestions. They've been so helpful. And, as it's turning out, spot on!

Make sure she has a bit of cash in coins in case they have a trolley coming round with snacks and newspapers.
