I love, love, love Victorian cotton batiste nightgowns with lots of lace, pintucking, embroidery and ruffles. I wear both long and shor lengths. I have silk chemises, as well. When I was pregnant or nursing, I wore soft cotton chemises (summer) or t-shirts (winter) because they were easier to wash & wear. No handwashing or ironing needed!
Dh loves them and I wear these as much for his pleasure as for mine.
When I was younger (and still living at home), I usually slept naked (with a robe at the foot of the bed). After I married, sexy nightwear was (and, is) more flirty and fun.
