Why was White men hitting on me all yesterday and why is that so?

I don't go out as much, but when I do white men likes me and start saying ooooowwwweeee, and I get black men doing the same too. But yesterday I had wore spandex pants with a T-shirt like all girls would wear, but they act like they never seen a before, I live down south where it is alot of big s, but I just don't know why they act like mines is unique, I know I do squats and workout an stuff, but the white guys be like Damn you have azz! Why is this so? I am a young black woman but down where I live they don't approach black women like that much and I dress just like any girl would, but people down here act like I dress different no matter how normal I dress.
