I hope your group will join the worldwide wave on World Tai Chi & Qigong Day each year, 10 am local time, worldwide ... always on the last Saturday of April. See WorldTaiChiDay official website for details, newsletters, and to list your group in the Events and Classes Directories.
You should try once without single jerk..same smoothness in moment..perfect stance..balance.. You will realise how hard to balance yourself. I feel peace while I performing same...the rhythm of music..moment..steps.. Its divine experience. Again it all depends on your faith of art,or even prayer for god is also useless. About silk or other uniform!! I wear short and t shirt ..it doesn't matter . Regards dear
