Random thought no.4
Why does Sherlock wear a dressing gown over a shirt and trousers inside? Over those lovely pajamas I can understand, but over normal clothes?
Also did anyone else notice that in Hound he puts his dressing gown over the same shirt that was covered in blood thirty seconds previously, but is suddenly miraculously clean. Unless of course he has a whole wardrobe of identical shirts. I wouldn’t put it past him.
I think it’s a nod to Victorian canon Holmes. Back then it wasn’t entirely uncommon to come in from the outdoors, take off your overcoat or suit jacket, and put on a nice dressing gown to relax.
A dressing gown (for men) or a housecoat (for women) is a loose, open-fronted gownclosed with a fabric belt that is put on over nightwear on rising from bed, or, less commonly today, worn over some day clothes when partially dressed or undressed in the morning or evening (for example, over a man’s shirt and trousers without jacket and tie).

It might also be that heating tends not to be great in old houses and he’s kinda cold in his shirtsleeves. 😀
He probably does have a whole set of good white dress shirts. Anybody who wears as many suits as he does would need to.
