I was thinking more of the "morning after" scene, all passion spent, where it would be realistic for them not to be dressed.
I know what you mean, but they don't just wake up with a little petting, the do another love PDD! I agree it looks strange both of them lieing in bed fully dressed after their wedding night. Indeed I didn't see one shirtless Romeo in any of the famous choreographies. So take his shirt off and give him fleshtone tights, some kind of semitransparent thin night gown for her, that's enough for phantasy, and remember he has to leave hearing the lark. Just redressing the shirt is enough.
