Every one of Dior's ten nearest neighbors by audience shape is a Fashion brand — a uniformity that is itself the finding. Similarity here measures how closely two entities' audiences resemble each other in composition; across the top 10, that composition is locked onto a single subcategory without exception.

The cluster runs tight and high. Gucci (social) leads at 0.97, followed by Dolce & Gabbana at 0.96, Valentino at 0.95, Fendi at 0.95, and PRADA at 0.95. Armani (0.95), Burberry (social) (0.95), Lacoste (social) (0.94), Versace (0.94), and Marc Jacobs (0.93) round out the set. The spread from first to tenth is only 0.036 — a narrow band that defines the flat shape. No single neighbor dominates; the entire tier is elevated and homogeneous.

What the shape reveals is that Dior's audience is structurally indistinguishable from the broader luxury and contemporary fashion peer group — the audience that follows one of these houses tends to follow the others in nearly identical proportions, leaving no meaningful gap between Dior and its nearest neighbors.
