Why do girls wear crop tops then hide their belly button?

Anonymous
I have seen this a lot from female friends and girls when out - they pull up their jeans/bottoms if their belly button is about to show. I haven't got an issue of course but I think it's rather counter productive, if you wear a stomach revealing outfit, why hide half of it lol?
Maybe the belly button is sacred or you girls see it as sexual? Especially when most now go through the effort of having a belly button piercing, presumably to show off.

Please shed some light on my ignorance lol (preferably girls), thank you!
