Amazon and type in 'cotton pajamas for women'. They had some cute ones.

I just bought a couple of those off of Amazon myself. 100% cotton is my sleepwear preference for summer, but I haven't been able to find cotton nightgowns in stores for a while now, for some odd reason. Found just what I wanted in Amazon with a quick search.

If you want to see the ones I bought, put in this in the Amazon search box: "PNAEONG Women's Cotton Nightgown Sleepwear Short Sleeves Shirt Casual Print Sleepdress"

They really are like a cross between a nightgown and a t-shirt, and there are lots of colors and patterns to choose from. Definitely appropriate for mature women (I'm 72 myself).

Great and beautiful nightware for summer and winter. She will love it.

and some are on sale now.
Top quality, free shipping if order is $65 or more. (I add in a few frivolities which then cost little or nothing.)
I'm a few yrs older than your lovely wife, and find items at Vermont Country Store that unavailable elsewhere.
Ex. foodstuffs, perfumes that we remember from back when, etc.


Good luck. She'll love whatever you choose.

Short, long, sleeveless, short sleeves. Many have a touch of lace or a bit of ruffles. Feminine but modest. They’re rather pricey, but it sounds as if you think she’s worth it.
