Why are some American women such slobs?

I do not mean all I mean some. I am an immigrant from Spain and I 've noticed some American women are just very sloppy in their dress, behavior, etc. In Spain it is rude and piggish even for a man to burp...I cannot tell u the number of times I've heard women burp in public here lol. And the fashion is very bad. American women love wearing their disgusting flip flops and sweatpants. In Spain these are only worn at the beach... I just think Spain and other foreign countries women present themselves better. In Spain the women are much more petite and lady like. They dress to the nine and don't burp and fart like pigs. Please offer ur thoughts
