My younger sister is a lot prettier than me and taller, but I get more male attention. Why is that?

Why do guys approach me more to talk than her? She's 5"7. I'm 5"4. Our body types: She has bigger boobs and a flat butt. I have a smaller waist, small boobs, wide hips, and a round butt. She's pale skin while I'm tan.

Our friends always call her the 'pretty one'. They even say she could model.
