Which dance form should a couple perform at Prom?

Essentially, the one you're both most comfortable with. If the dance is a huge struggle, or an embarrassment, then you're not really enjoying the prom. But perhaps you're asking which dance form will impress most?

Anything danced with style, and preferably with neat, swift foot movements. A synchronicity in body movements is also rewarding to watch but requires work. So get practising!
