The prairie aesthetic is hand-down the most ubiquitous dress and sleeve silhouette of the past two years, and it's only getting stronger this Fall. While they go by "balloon sleeves" for most of us, there are actually three types of sleeves that we've been loving this year. The longer sleeve with a balloon-shaped centre and tapered wrist is called a bishop sleeve (as featured in the photo above), while a bishop sleeve with wider tapering at the wrist is called a cuff. Sleeves that are more voluminous at the shoulders are called a leg of mutton, or simply a mutton sleeve. And the shorter, cute sleeves are called puff sleeves.
