Trinny and Susannah's Body Shape Measurement

For a long time I'm thinking about the how could I encourage the user to input their personal body shape data for interaction.  Transitional solution is to ask the user to measure the BWH(breast, waist, hip) number, but it's kind of inconvenient do to this cold hard fact.

After the meeting with Ms. Stevenson,  I began to look back to the lessons by Trinny & Susanah, and find this lovely quiz. I think it's easier to animate and interacte using these measurement. Later I will do an experiment on it.
