Where can I find a plain cotton sleeveless knee-length nightdress?

[NCG161280]

Please help. I’m trying to find a nighty that is:
100% cotton
Sleeveless but not strappy i.e not with adjustable straps that slip
Not white
Has no bows or cartoon characters on it
Doesn’t look like a Victorian grandma would wear it
Knee length
Size 18/20
I have looked everywhere!

I know. I used to be able to pick up exactly what I wanted in asda, M&S or sainburys. I don't want nylon, nor see through white or it so short I can't bend over!

Also a bit longer than you want, but reduced, in your size in cotton/modal, & a pretty colour.

Oodie have started doing sleeveless nighties

Ditsy Floral Scoop Neck Nightie – The Oodie UK https://share.google/8g2OXH8FnR532ARYE

They have strappy ones as well as these, not sure what style you are after

any reason why you wouldn't just get T-shirt dresses?

£28, loads of colours: https://www.roman.co.uk/sea-shell-print-midi-dress-14922280

More stripes, 3 colours, £18. I'd get these! https://www.roman.co.uk/ribbed-stripe-cap-sleeve-midi-dress-14656060

These are long and viscose / linen / lyocell / cotton / modal - just throwing them because they're quite a stylish shape and would be cool for sleeping. £34 for two.

I have been pleasantly surprised by the nightwear available in Peacocks. Perhaps worth a look?

^ just realised you stipulated cotton.

These are great. I'm usually a pyjama person but got them for a hospital stay. They've been a godsend for wearing indoors in the heatwave.

I presume nightdresses don’t sell as much as pajamas do unfortunately. I did see this one in the sale.

These are lovely - they've been perfect in the heat this summer: https://www.theirnibs.com/collections/night-dresses-and-shirt

Woolovers only available in XXL

These are lush - thank you!

Sorry these are way too old fashioned, I’m only 45 😍

Love these but why so expensive? 🤔

These look perfect thank you!

Cyberjammies! I had the same wishlist and stumbled across them. Ive now got about 6 of them.

I like these from Amazon:

Those Oodie ones are not cotton.

On the rare occasion one does find a cotton one, it’s often cotton jersey, which I don’t want.

The Edinburgh Wool website have got some short sleeve ones.

I am very tempted by this.
I found this at John Lewis & Partners. What do you think?

I have the Cyberjammies £29 swan one in a different colour and it is fantastic. It is really light and cool, does not cling to the body but glides over everything without being a swing style. I got it in M&S but Cyberjammies own site has a 15% discount for first time buyers.
