Attracted to my waist?

sometimes-epecially when i am wearing a crop top or a bikini- i feel like guys get attracted towards me by the appearance of my waist (belly, belly button). I wanna know if this is only imagination or real. I feel like i can see it by them looking at there and the size of the pupil of the eyes getting bigger (dilated eyes it is called i believe).

What y'all think? Is this real kr imagination? How can i tell if they are attracted? Does any girl had similiar experiences?
