I'm starting with a side thought, because this is my space.
In this commercialized world, we are often pushed to think about what attire to wear on our bodies. Clothes can help accentuate who we are and also serve as an outward expression of us. Oftentimes it does. What I love about dance is that our souls with our bodies are at that podium. When it comes to dance and attire, in my opinion less is more. When shooting with somebody I want to have the dancer's core speak. I want their soul, working in unison with their body to whisper, shout, cry, mumble, rejoice. The clothes should not constrict the dancer unless it is particularly supposed to.
Moving onto movement.
