In days gone bye my wife and I use to shop for lingerie for her in mid-town Manhattan. It was always a fun outing. Then kids came along and her sexy nightgown came off after a romp in the hay. Decades have passed and see is comfortable in PJ's; tops and bottom. There is still some of hers hanging in the closet; not many, but a few. When she was cleaning out the ones that no longer fit, which unfortunately was most, she told me to take what I wanted. That shocked the heck out of me. She knew I would take the white peignoir I bought for her back in 1971. She had found me wearing it one night because I like the feel of the nylon.
Anyway, because of medical issues we sleep apart. She in her warm PJ's and me in one of my 41 nighties, all nylon. Right now I have on a pink Shadowline sleeveless, ankle length nightie from their Rose Bud line.
