You can also sleep in woman's sleepwear. There are all kinds of materials, styles, lengths, PJs, "sets" (maybe a short top, tank, pants, shorts) that can fit the changing requirement of temperature, mood, and your appearance preferences.
I am still in my blue floral cotton long gown, it is very soft, smooth, and extremely feminine.
It has nice touches such as pintucks, and it keeps me warm. It is not too hot to wear even in the summer.
I realize that many live with others so discretion is needed in the privacy of your home. If you have the ability to dress in a pretty sleep shirt or a gown, this can be quite affirming.
