I apologize for not having explicitly denoted, somehow, the facetious nature of my remark.
A universally accepted form of punctuation has not yet been created for that purpose, and so one must rely upon the interpretive capacities of others in such situations.
It's a shame, really.
That having been said, would snark have been appropriate even if the interest were genuine? We are, after all, poring over the components of a prince's wardrobe and the ways in which each item is maintained and laundered. It wouldn't be unheard-of for someone to appreciate such a small detail, given the context.
