As the soul accessory in men's wear matching, tie selection requires integrating fabric science, craftsmanship aesthetics, and occasion etiquette. Based on Savile Row custom standards and international textile association data, this article systematically analyzes the physical properties of 6 core fabrics including silk, wool, and knit (such as mulberry silk fiber diameter 10-13μm, wool scale spacing 70-80nm), revealing key points for identifying craftsmanship like hand-rolled edges and horsehair linings (stitch pitch ≤3mm, gloss 35-55GU). Through the proportional formula of tie width and collar (e.g., Windsor collar fits 8.5-9.5cm ties) and the optical color matching rules (Munsell lightness difference of 2 levels), it constructs precise purchase models for scenarios such as business formal wear, wedding banquets, and casual daily wear. The article concludes with cleaning and storage specifications (e.g., professional dry cleaning for silk at ≤30℃) and solutions to common pitfalls, helping you shape a professional image through details and making the tie the ultimate carrier of style expression.
