They can both explain the evidence. Tagged gifts certainly do. But even untagged gifts fit the evidence IF PR knew which paper she used for Jenny. When I wrap family Christmas gifts, I use different paper for different people; I don't always have to tag them. My daughter, grandson, etc. each have special paper. And most people use cute kids' paper- which is usually gender-specific. I am not stating as fact that PR did this- but IF she did, it can explain that she had an idea where the panties were, even if the boxes were not tagged.
