Just some food for thought: Men not being into fashion is a relatively new phenomenon, and like all things is part of an historical cycle. Men were VERY into fashion throughout the 1500s, and remained so until the strict puritanism of the early 1600s coupled with a backlash against the aristocracy led to much more conservative dress. In the United States and England, men’s fashion was again very important and flamboyant during the latter half of the 1700s until around 1810-1820, when men’s fashion become more muted in the aftermath of the Napoleonic Wars and the republican revolutions. Men again were more fashion conscious in the 1840s-1860s, but in the Victorian age, there was again no real men’s fashion to speak of (think plain black frock coat, pants, waistcoat, and hat). The roaring 20s were again a time of high fashion for men, but the Depression and WWII put an end to that – a plain and conservative trend that continued until 2005 or so. Since then, men’s wear has become more varied and fashionable, more unique and individualistic.
Its just a revolving trend. Go with it.
