Collection: Extreme Cashmere

"Extreme Cashmere – Sustainable, Genderless Cashmere Essentials
Extreme Cashmere redefines luxury knitwear with a bold, inclusive vision: timeless cashmere pieces designed to fit everybody and every body. Founded in Amsterdam by Saskia Dijkstra in 2016, the brand set out to make the “perfect sweater”, and a single-size crew-hop sweater unexpectedly fit nearly everyone. This sparked the creation of a genderless, unisex, one-size-fits-all concept that defies conventional sizing norms.
Expertly crafted from high-quality Mongolian cashmere, Extreme Cashmere’s knitwear is celebrated for its form-meets-function design, tight knitting, minimal chemical treatment, and deliberately oversized sleeves that adapt naturally to diverse physiques. The brand’s minimalist aesthetic, rooted in simplicity, comfort, and understated craftsmanship, embraces modern luxury with thoughtfulness and authenticity.
Extreme Cashmere eschews fast fashion cycles and seasonal trends, favoring timeless styles.
Exclusively available at BY Marie, these pieces blend urban elegance with conscious luxury.
