Brooks BrothersClassic Fit Wool No. 1 Sack Tuxedo

Two Brooks Brothers icons come together in our No. 1 Sack tuxedo, uniting the natural ease of our historic sack silhouette with the exceptional craftsmanship of our flagship tailoring collection. Pure barathea wool from England's renowned Abraham Moon & Sons is tailored with the No. 1 Sack's signature undarted front, center hook vent and two-button sleeves, then elevated for evening with a grosgrain shawl collar, covered buttons, and coordinating grosgrain details on the pants. Crafted in Italy with internal half-canvas construction that forms to your build, it features hand-tailored arm openings for comfort, fully stitched craftsmanship for longevity and framed interior pockets. The wool's natural stretch allows ease of movement, while meticulous construction creates a beautiful lapel roll and drape for an exceptional fit. CLASSIC is our standard, best-selling fit, designed for a wide range of body types. 1-button Center vent Shawl lapel Fully lined - 100% Wool
