Around 200 years ago, men stopped wearing exaggerated clothes and men who still took an interest in fashion were made fun of and called fops or dandies so everyone collectively started to wear the same dark suits and the irrational male fear of fashion began its reign because guys don't want to be thought of by other guys as being "feminine".
EDIT: The first picture in your post is actually from a print making fun of men who are interested in their appearance.
