As I understand it [forgot where I read this] ALL clothing, including underwear were labled one way or the other. They were also laundered separately from anyone else's. When the soldiers were looting the clothing, after the executions, one was said brag that he had Nichola's underwear. Better than he ever had before, no doubt. Wives girlfriends received the women's clothing, including underwear, bras [not sure ifthey actually wanted corsets though].
