Butterfly sleeve is a beautiful sleeve with a puff on top and slightly loose at the hem. It is basically a puffed sleeve but one that doesn’t taper off like the normal puffed sleeve, nor ends in a cuff. It has a very elegant look and is usually paired with low cut gowns. It is a sleeve which is seen in the national costume of Philippines and made popular by the former first lady Imelda.
