If the lady takes up the correct position with her partner in Modern Ballroom , and has Jonathon said. "Don't crunch your side". You should be looking at the world with your right eye, on a clock face at 2 and your left eye at 8 or there abouts. The mans eyes will be horizontal. Beginners get some advice on this, whatever you do don't bend from the neck. Think of a piece of bamboo where every section bends equally. I tried this with a tape measure. even though I bent the piece of cane, the distance on the tape remains the same.
