Dance square dance dance posture is not good to have any tricks?

Last night I just watched the square dance mothers, leading the dance is very good, the rest are supporting the role of the movement amplitude, not too conservative, and then is the movement to be skillful, the movement can not remember how to dance well? I dance every time I dance to the mirror to dance, which is why the dance studio is a big big mirror, not everyone a move is very beautiful, more to the mirror to correct the contrast, you will be more and more good-looking, and then there is a requirement for physical flexibility, which is innate, thank you.
