This is traditionally finished at both edges with a contrasting warp (most commonly red); that is why this type of denim is sometimes referred to as red selvedge.
Both had their own zero-waste selvedge to selvedge pattern-making methods, both favoured the use of natural materials such as silk and wool, which could biodegrade.
The men's styles -- arguably more tongue-in-chic than the women's -- include glow-in-the-dark denim and a new selvedge herringbone in addition to linen and cashmere blends; prices ring in at about $200.
