That depends, if I am getting undressed to have a sexy time, or if Im getting undressed to take a shower.
pretty much random. shoes first of course, if i'm wearin em. socks next generaly, again if. pants and shirt in either order. (underwear?, what's underwear? something i'd probably wear occasionaly, thermals that is, if it was getting that cold and i lived where it did often enough to have them). coats and shoes tend to come off first thing i'm back in the house. so they don't really count when it's time to get naked to go to sleep or whatever. =^^= .../\...
It's pretty random really. Trousers and socks usually come off at the same time, then top... bra... knickers.
