The Ballroom style is considerably different as can be seen in the clip below from the World Championships Professionals in 1979. The Ballroom style originated in the mid 1930´s Germany when couples decided to change the stance to something closer to the typical Ballroom stance & make it look staccato & the top of the ladiesī left thumbs should make contact with their partnersī right armpits.
The video clip below from the film "Take The Lead" captures the original character of the dance brilliantly. Performed by Antonio Banderas the story is about Pierre Dulaineīs work in America as a professional dancer. Antonio is not a dancer by profession, so he must have worked incredibly hard on the choreography below to make it look so good. It must have taken ages for him to learn & rehearse.
If you think that was good, you should see the following clip.
