How Did Belinda Blumenthal Cover Up in the Lobby?

Belinda is completely naked while Peter Rouse is completely dressed, and the hotel camera is still on them. She laughs and says, "Pass me my riding jacket and boots." The jacket covers her breasts. The leather boots cover only her lower legs and feet. Peter calls the result very daring. The hosts point out that the boots do nothing for everything the jacket leaves bare. He picks up the unfinished wine in its ice bucket. Walking past reception, they ask the young man there for a nightcap as well as another bottle, and he pours them each a brandy.
