I think it’s just performative. British Vogue doesn’t caption all of its posts this way, just a select few. Selective accesibility? I could be mistaken; there could be a population of profoundly blind people rushing to Instagram to hear a description of how the latest cover subject of Vogue is displaying her bright red nails and standing in front of a neutral-color studio backdrop, but I seriously doubt anyone has asked for this.
I like the cover. Sza looks good, the styling feels seasonally appropriate.
