Zahiraah, very true, posture is also very important.
And Costuming ofcourse lol!! Selkie, great for bringing it up, I totally forgot to mention that very important concept of a good performer. Costume must be appropriate for the occasion and flattering to a dancer's body, and very important: NOT TACKY!! As Selkie said, no see through skirts or no "no-skirts at all"... wear something underneath, NO weirdly placed tassels..
