The Brook Taverner One Mercury Waistcoat combines timeless tailoring with practical versatility. This single-breasted design features five buttons for a refined silhouette, whilst two front welt pockets provide functional storage without compromising the clean lines. The lining-backed construction ensures durability and maintains shape through regular wear, whilst the contrast lining adds a sophisticated detail visible when layered. An adjustable back strap allows for a customised fit across different body types, making this piece accessible to a wider range of wearers. The machine-washable fabric simplifies care and maintenance, eliminating the need for professional dry cleaning. Designed to coordinate seamlessly with the BK401, this waistcoat works as a standalone piece or as part of a coordinated ensemble, making it an essential addition to any professional or smart-casual wardrobe.
