The price is primarily driven by fabric composition (e.g., wool percentage, cashmere blends, or high-tech synthetic fibers), construction complexity (double-faced wool vs. lined polyester), and order volume. For instance, a handmade double-sided wool coat will command a significantly higher price point than a mass-produced trench coat. Additionally, seasonal demand and current fashion trends in the Seoul market often dictate the premium placed on specific silhouettes like 'oversized' or 'minimalist' designs.
