ISAIA For Sir Wilson Dark Gray Flannel Lambs Wool Business Suit

We are pleased to offer pieces sourced from Sir Wilson: often vintage yet preserved in remarkable, new condition, they are increasingly rare to encounter. In a retail landscape driven by branding, these garments stand apart: quiet, enduring, and exceptionally difficult to find today.

Founded in 1973 on Turin’s Via Roma, Sir Wilson is a quintessential example of the Italian multi-brand menswear boutique—discreet, highly curated, and grounded in a philosophy of timeless style. Rather than chasing trends, it built its reputation on a careful balance of Italian and British tailoring traditions, offering garments defined by quality, restraint, and longevity.
