Quality Winter Coat Buyer's Guide & Vintage Sourcing Service

An information resource (e-book or online course) teaching consumers how to identify genuine high-quality wool and cashmere coats, understand fiber blends and properties (like pilling), and spot good vintage pieces. It would include curated lists of reliable new and vintage brands within various budget ranges. Optionally, a concierge service could help users find specific coat types from vintage markets based on their criteria, addressing the struggle to find quality without synthetics.
