It's easy to move your legs if they're (spats) about this length.5 bun-dake (half length) spats are commonly called "half spats".Spats (leggings)3/4 length and 1/2 length versions are strongly associated with competitive use.1/4th and 3/4th length spats are colloquially called "water spats"These are about 1/4th length.You'll often see tight pants through leggings.Half length spatsA crop top jacket is just right for exercising.Leggings really dig into the waistline.Spats are characterized by their snug silhouette that extends from just below the knee to the ankle, and are commonly worn as sportswear or for fitness purposes.My theory is that one-quarter length leggings are essentially hot pants.
