Every issue of La Belle assemblée had a beautiful woman on the cover, "photoshopped" in effect by an artist's hand. They were all celebrities, but also royalty and therefore politically powerful.
When your celebrities are movie stars I suppose you consider it fashionable to be informed of their latest movies. Likewise, when your celebrities are politicians, politics becomes fashionable for you.
How much of a person's "depth" is just just chasing after what is fashionable; chasing after stars?
