Butterfly Sleeve Explained
A butterfly sleeve is not just a flared sleeve. It is a cap of fabric engineered to hold a wing shape from shoulder to elbow. Learn the cut, the construction, and where the silhouette earns its name.

What a butterfly sleeve is
A butterfly sleeve cascades outward from the shoulder cap in a wing shape, narrowing only slightly toward the elbow. The hem is often scalloped or asymmetric. From the front the wearer reads as having wings; from the side, as having structured architecture at the shoulder.
The shoulder cap
The wing is held in shape by the shoulder cap. The cap is reinforced with a sturdy interfacing (sometimes a thin boning strip is hidden in the seam allowance). The sleeve fabric is cut on the bias so it cascades cleanly rather than collapsing.
Butterfly vs puff
A puff sleeve is gathered at the shoulder; the volume is in the top. A butterfly sleeve is structured at the shoulder; the volume is on the outside. A puff says soft; a butterfly says architectural.
