The top 10 neighbors for Hourglass Cosmetics are drawn entirely from a single subcategory: Beauty brands. Scores run from Stila Cosmetics at 0.88 down to Milani Cosmetics at 0.83, a range of just five points across all ten positions — the defining characteristic of a flat shape.

Similarity here measures how closely two entities' audiences resemble each other in composition. The cluster spans a wide price spectrum within Beauty, from MAKE UP FOR EVER (0.86) and Tarte Cosmetics (0.86) at the mid-to-prestige tier, to BH Cosmetics (0.86) and MakeupGeek (0.85) at the accessible end, to NYX Pro Makeup US (0.84) and e.l.f. Cosmetics (0.84) as mass-market entries. Urban Decay (0.87) and Laura Mercier (0.84) round out the set. No non-Beauty brand, no celebrity, no media channel appears in the top 10 — the neighbor set is entirely same-kind.

The flat shape and uniform subcategory composition together indicate an audience that reads as a core makeup consumer: recognizable to the full range of the Beauty brand category, without a strong pull toward any single adjacent space.
