Putting on a Show of the Blues
This is an additional instance of a so-called “mistake” that was most likely carried out on purpose. Anyone who looked at it would be able to tell that the top of your skirt was sheer because of how it was constructed. Did she not look at herself in the mirror one last time before she stepped out of the house?
Before the woman left, certainly one of her employees would have let her know that others might see what she was wearing and that information would be shared with them. The fact that the briefs are a pair is a further consideration to take into account. There is no way that she could have worn the sheer Givenchy outfit without knowing it, but it showcases her figure well.
