Calvin Klein X Slim Fit Infinite Stretch Vest in Navy — Size Medium

Calvin Klein is the definitive American premium fashion label — a brand whose design philosophy of clean lines, refined minimalism, and understated sophistication has made it one of the most recognized names in global fashion for over five decades. The X Slim Fit Infinite Stretch Vest is a premium suiting vest built on 100% Stretch Wool — a garment designed to anchor a three-piece suit combination or to serve as a polished standalone layering piece in smart-casual and business casual contexts. Brand new with tags. Please note: sizing is based on measurements as the garment is not marked with a size internally; based on flat-lay dimensions this fits a Medium. There are also three small holes on the inside bottom lining from a removed tag — these are on the interior lining only and are not visible from the outside when worn.

The 100% Stretch Wool construction is the material specification that gives the Calvin Klein X Slim Vest its premium suiting character and all-day wearability. Stretch Wool combines the natural breathability, rich surface depth, and authentic suiting drape of premium Wool with the four-way give of an elastomeric fiber — producing a vest that holds the structured, clean silhouette of a suiting vest through a full day of seated and standing professional wear without the rigidity that a conventional non-stretch Wool construction imposes. The Navy colorway is the most broadly authoritative and versatile a suiting vest can carry — a deep, clean navy that pairs naturally with matching Calvin Klein suit separates, with solid navy or charcoal trousers for a mixed suiting combination, or with a formal shirt and tailored trousers as a standalone smart-casual layering piece. The Calvin Klein X slim fit is the brand's most fashion-forward and body-conscious suiting cut — a precise, contemporary silhouette that reads as intentional and design-aware in every professional and elevated casual context where a vest commands attention.

Style & Care

The Navy Stretch Wool construction and Calvin Klein X slim fit make this vest a versatile and premium layering piece for formal, business professional, and smart-casual dressing — wear it as the third piece of a three-piece suit combination with a matching navy jacket and trousers for a formal occasion where the vest adds a layer of sartorial sophistication, pair it with a crisp white dress shirt and well-fitted charcoal or navy trousers for a smart-casual layering look where the stretch Wool drapes cleanly and the Navy reads as polished and authoritative, or use it as a statement layering piece over a slim crewneck for a contemporary fashion-forward casual combination where the Calvin Klein vest construction does the talking.

• Care: Dry clean recommended to preserve the Stretch Wool's natural drape, structure, and the integrity of the Navy colorway. Store on a padded hanger to maintain the vest's structured shape. If steaming between wears, use a low-heat steamer to smooth without direct iron contact on the Wool surface.
