I don't understand what the value of explaining to a visually impaired person what dress you're wearing is. When you say things like "Anna is wearing a black maxi wrap skirt printed with various sized white stars and a white ruffled crop top," it assumes that the reader knows what any of those things look like. If someone is visually impaired to the point of needing a verbal description, how would they know or care what any of these things look like or mean?
