"What?"
Hilarious!!!!
Ok, so a few things you should do before asking us or even writing anything:
You need to define what a "skinny" women is, give one or more prototypical examples, and use other measures like BMI or whatever so that it is clear to everyone, including yourself and the professor, what a "skinny women" verse a "heavier women" is. Do the same for heavier women in regards to prototypical examples and BMI and other measurements, ect.
Because otherwise I'm not sure what you mean; how skinny, how heavy, ect?
