Transformation process:
1: the jeans is floating in the air
2: the jeans transform to a paper
3: paper retransform to a filament 
4: the filament transform to a man who wearing the jeans
5. the man transform to a woman who wearing the jeans
the details for the transitions can be discussed but we would like it more detailed and realistic.
And basically the CG treatments will be at the end of the Video, we hope the 3D motion could match our whole video concept: looks advanced.
