Son of a Tailor launched in Copenhagen in 2014, built entirely around a made-to-order model rather than the usual stocked-inventory approach. Every piece is produced only once a customer orders it, sized by a proprietary algorithm that turns basic body measurements into a custom fit across 24 pre-engineered sizes. In 2023 the company opened its own production house, SON Supply, in Santo Tirso, Portugal, giving it direct control over quality rather than relying solely on outside manufacturers. The brand sticks to mono-fiber fabrics like 100% cotton or wool wherever possible, a choice made specifically to keep garments easier to recycle at the end of their life.
