## Overlaps & pitfalls
A collar could combine materials (e.g., leather with rubber trim), but the primary material determines classification. If unsure, prioritize the dominant material by weight and surface. No option is inherently more “fetish” — all are valid for fetish use. The main function (e.g., bondage, decoration) doesn’t override material classification
