Why don't people like overalls?

I think they are good for kids not adults the reason I put them on my child because there cute and easy when u grow up it is are duty to put thought and creativity into what we wear find your own style and any one piece outfit takes that away there is no thought process in one piece outfits what colors go with what what kind of neckline works best with your chest what kind of patterns go best with your frame see that's why I think overalls are a no no for grown people
