"Modest" nightwear and pjs

[Notagoodnight]

My DS(14) has a developed a condition that means he needs round the clock male support staff. I have realised that this means DD(26) and I have a desperate need for some sleepwear that is "modest" and better quality than our usual primark stuff!

I'm looking for long nightgowns in slightly stretchy fabric, a long lightweight definitely not see through dressing gown that is easy to get on quickly, and a long definitely not see through must stay closed dressing gown without a waistband that I can sit in comfortably. They must be lightweight as the heating is on these day much more than it used to be.
Any recommendations?

@Notagoodnight I hope things at the very least settle down for you. I have spent many many months in hospital with DD and when she was on a ward felt very exposed with dads sometimes staying the night ( it tends to be mums). So when she first got ill I got 3 sets of M&S pyjamas in cotton and a nightie too. I have an old wrap cardigan which I always wear on top and Ugg slippers. Although DD rare goes in now she's an adult ( though 4 months chemo a few years ago) I keep a decent pyjama set in my always packed hospital ready to go!
