I’ve got a whole wardrobe of nightwear, because of my situation, although I never wear any of it in bed!
Pyjamas usually always (used to be!) from Long Tall Sally.
Amazing fit/length and excellent quality which wears so well and not bad in a sale. Pricey if not but worth I would say?
But since they were bought out by ‘Yours’ clothing, they’ve gone all polyester and cheap looking - but not cheap in price!
Otherwise I like Next (tall) pyjamas (these seem to vary a lot these days not bought in a while!) and all-in-ones - including a couple of black velvet ones which are more lounge-wear.
Nightdresses I do like Marks esp their Modal designs - though usually off eBay and nothing recently.
For cheapo nighties, both George and Tu are good and choose viscose, or cotton.
And John Lewis and Oysho (Spanish brand linked to Mango) both good for “dressier” or cuter items but only in the sales!
If I won the lottery, I’d like to waft about in White Company pieces!
I’ve got one Carole Hochman kaftan type thing which I was given and it has worn well, it’s useful although the length is a bit dodgy on me!
Plus I bought a pair of her short sleeved, short cotton stretch t-shirt nighties (with bra “shelf”) which I bought new off eBay and I have to say the quality is really very good!
I wear more as summer dresses...
My mum was given some of her fleecey PJ sets and I think they look cheap and gave bobbled quite a bit. And I know they weren’t cheap!
Sorry, bit of a specialist subject of mine, night and lounge-wear!
Just don’t get me started on dressing gown, robes and wraps
