For some, you've kept up with the times. Others are stuck in one specific decade. Either way, it's fun to take a look at how men's fashions have changed over the last 100 years.

One of the best things about men's styles over the last 100 years, with maybe the exception of parts of the 1990s and 2000s, looking sharp is pretty much the standard.

The other great thing about menswear is classic never goes out of style. And mixing classic and contemporary styles not only sets a guy apart, but if paired correctly creates a look that can really stand out in a good way.

There are styles, like those from the 70s disco era, that should never return. So if you still have a leisure suit, platform shoes, a polyester shirt and it's not your Halloween costume, get rid of them.

However, if you unearth a snazzy sweater vest from the 1940s, you can score an amazing look today.

While some question boxers, briefs or boxer briefs, If this 100 years of men's fashions is true down to the underwear, it appears you can never go wrong with a pair of tighty-whiteys.
