what fictional characters habitually slept in the nude? (not just after “nookie”)
Prince Rupert of the Forest Kingdom and Princess Julia (aka Hawk and Fisher).
Adam & Eve.
Mrs. Peignoir.
Patrick Swayze in Roadhouse.
Pretty much every character in the the later Anita Blake books.
Probably most of Heinlein’s characters, at least in his later years.
Any book with a medieval setting, assuming they’re historically accurate.
Ginger Grant.
All the male SaDiablos in Anne Bishop’s Black Jewels books.
James Bond did in the Ian Fleming books
Emmeline Fox, from The Crimson Petal and the White. It’s actually mentioned as a character point, that this prim and proper Victorian lady chose not to dress for bed one night because she was too exhausted from illness, and then kept doing it after she was well (as well as hanging around her house nude when awake).
Eric Forman from That 70s Show, Grandpa Walt Finnerity from Grounded for Life, and presumably that nudist couple from Family Guy.
Marge Simpson!!!
Joey: …I can’t sleep in my underwear.
Chandler: Well, you’re gonna!
Lassie.
Angel, in Angel.
Kinsey Millhone.
Megan Fox
Terry Bradshaw’s charcter (the father) in “Failure to Launch.”
