I wish cartoonists would pay more attention to what people wear. Clothes are funny (above), though you'd never know it by looking at modern animation and newspaper strips.
A hundred years ago main characters were drawn like clowns with outrageous clothes. I admit that's going too far, but I prefer that to the bland clothes cartoon characters wear today.
The way I see it, characters should always dress to fit their occupation or physical type. Rich people should look rich, poor people should look poor. Texans should look like cowboys, fat people should look like opera singers, and skinny people should look like scarecrows.
Cartoonists should exaggerate. Slightly rich people (above) should look and act very rich. Sneaky people should dress like professional sneaks, and not simply act that way while dressing normally.
Unfortunately we live in an era whose fashion is dominated by geniuses like Calvin Klein. Klein set himself to the task of making the common man look as elegant as the rich, and he pretty much succeeded. Now every working person looks good, but nobody looks funny anymore.
Er...well, maybe some people do. Thank God for emos, skaters and hip hoppers.
