Men’s 3-Piece Suits
Men's 3-Piece Suits
A 3-piece suit is the most complete expression of tailored dressing, and Brooks Brothers has been building them since 1818. Each set includes a suit jacket, matching trousers, and a waistcoat cut from the same fabric, ensuring a unified silhouette whether you wear all three pieces together or carry the jacket. Our 3-piece suits are built in the 1818 Collection using heritage wool fabrics, with the waistcoat adding a layer of structure and formality that a two-piece simply can't match. Suit jackets and suit pants from the same collection are also available separately for mix-and-match styling.
What's Included in a 3-Piece Suit
Every 3-piece suit includes a tailored jacket, matching trousers, and a waistcoat (or vest) cut from the same fabric for a single, unified look. Wear all three pieces for the most formal presentation, or remove the jacket for a waistcoat-and-trouser combination that still reads as fully put-together.
The 1818 3-Piece Suit
Our 1818 Collection brings 3-piece tailoring back to its roots: half-canvas construction, precision finishing, and heritage wool fabrics built to hold their shape through years of wear. Shop 1818 3-Piece Suits to see the full collection.
3-Piece Suit Separates, Jacket & Pants
Prefer to build your own fit? Suit separate jackets and suit separate pants from the same collections are available on their own, so you can mix proportions or replace a single piece without buying a full set. New to 3-piece tailoring? Start with the Suit Guide.
3-Piece Suits in Every Fabric, Color, and Fit
Brooks Brothers 3-piece suits are available in the fabrics, colors, and fits that matter most. Wool is the foundation, structured, breathable, and season-spanning, with linen and cotton options available for warmer months and more relaxed occasions. Navy and black are the workhorse colors, with grey, tan, and seasonal tones rounding out the range. Choose Slim Fit for a contemporary tailored silhouette or Classic Fit for the traditional Brooks Brothers shape. Whatever the occasion or preference, there's a 3-piece suit in this collection built to match it.

3-Piece Suits for Every Occasion
A 3-piece suit signals intention, and Brooks Brothers builds them for the occasions where that intention matters most. For weddings and formal events, the waistcoat adds a layer of formality that elevates the look without requiring black tie. For business and professional settings, a Slim Fit 3-piece in navy or charcoal projects authority while keeping the silhouette clean and modern. For creative occasions, cocktail parties, gallery openings, important dinners, a three-piece in a seasonal fabric or softer color lets the suit do the talking.
