Flamenco skirts can be cut several different ways.   The best skirts for flamenco are slim-fitting around the hips and flare generously towards the hem.  This is usually achieved by using panels, which are very narrow near the waist and get wider as they go down to the hem.

Some skirts have more v-shaped panels (called godets) added round the hem for even more width.   A nice touch is to have the godets in a different fabric, which accentuates the movement to the hem.  A popular combination is a plain fabric for the skirt, with toning polka-dotted godets (or vice versa).

Another option is a circle skirt, but avoid styles where the circle starts at the waist - the bulk of fabric around the waistline isn't flattering, and it's not a flamenco look!.  Instead, choose a skirt that starts on the hip (rociera), or one with a tight-fitting basque around the hips and the circle starting from the bottom edge of the basque.
