capsleeve

Capsleeve is a sleeve style in which the fabric covers only a small portion of the upper arm and sits over the shoulder, forming a curved edge that follows the armhole. The term is common in fashion design and pattern making, with the spelling “cap sleeve” also widely used; modern product descriptions sometimes use the combined form capsleeve.

Construction and silhouette: A cap sleeve is created by a short sleeve cap that rises slightly above the armhole, ending at or just above the armpit. The fabric typically follows the natural curve of the shoulder, creating a minimal sleeve that leaves most of the upper arm exposed. The cap can be shallow and smooth or carry a touch of fullness for a subtle puff.

Variations and styling: Classic capsleeves are simple and clean, but variants may include a small puff or a slightly more pronounced cap to add shape at the shoulder. They are commonly used on blouses, dresses, and wedding gowns, and can be paired with a range of necklines from crew to boat to scoop.

Fabric, fit, and construction notes: Capsleeves work with both woven and knit fabrics. Stiffer fabrics create a more defined cap, while drapier materials yield a softer edge. Proper armhole shaping and a smooth cap edge are important to avoid gathers or unsightly strain at the sleeve cap.

Use and perception: Capsleeves offer modest shoulder coverage and can balance proportions on various body types. They are a versatile option for warm-weather garments and for styles aiming for a light, feminine silhouette.
