IMO no one compares to Kim Kardashian. That woman is absolutely gorgeous, from a physical perspective. I can think of no one who has her beat in the looks department.
I don't 'idealize' anyone, but I do have my own definition of what I consider beautiful. I'm considerably more harsh with women than men, but in general I find her facial structure attractive. She has nice cheekbones, and her nose and eyes are proportional to the rest of her face.
