This scene from Ocarina of Time comes to mind, but I'm not sure which frames; or pairs of frames; are best to use. This kind of trope is hard to demonstrate in a still image.
EDITED IN: Does it require swishing the whole cape, or only part of it? Half a minute into this video is a swishing of part of a cape.
