There's no shame in following a trend if the craze in question is belly dancing. Local shimmiers Kaya and Sadie are the finest of Denver's hip-undulating sirens; both are world-class belly dancers who've showcased their skills in instructional videos, in dance workshops and at a range of events around the metro area. And although the lovely ladies work impeccably as a team, each has her own unique style and can help you develop yours. Kaya and Sadie offer classes for novices and intermediate dancers alike -- but if you'd rather watch the booty-shaking than join in, you can check their site for upcoming performances. Go ahead -- belly up.
