As football has changed and evolved through the years, so have the cheerleaders.

Back in the 1960s and 1970s, cheerleaders stuck to leading the crowd and cheering on their teams with big poofy pom-poms.

Now, a lot of cheerleading squads have added on a dance element as well, and their outfits have gotten a lot ... flashier.

The Eagles cheerleaders debuted brand new, very skimpy, uniforms designed by Vera Wang. The trend of smaller and tighter seems to still be going strong.

The Baltimore Colts had cheerleaders in the early '60s.

And this is what the Indianapolis Colts cheerleaders' uniforms are like today.

Vikings cheerleaders take a break back in the '60s.

The Vikings cheerleaders pose for the crowd today.

The Denver Broncos cheerleaders at the end of the '70s — yes that's Robin Williams running out with them..

And the Broncos cheerleaders now.

Perhaps the most famous NFL Cheerleaders: the Dallas Cowboys cheerleaders in the '70s.

And the Cowboys cheerleaders now. They've probably changed the least.

The Jets cheerleaders waiting for the team to run out in the '70s.

The Jets cheerleaders now.

Here are the Bengals cheerleaders circa 1980.

And the Ben-Gals now.

Here are the Packers' cheerleaders in 1978. Unfortunately, they eliminated the squad 10 years later.

The Eagles cheerleaders wore leotards and had big pompoms in the late '80s.

And the Eagles now. Their uniforms are brand new this year and designed by Vera Wang.

The late 80's showed a trend of full leotards. Here's a San Francisco 49ers cheerleader in 1988.

Now the 49ers go for the two-piece as well.

But the Raiders (Los Angeles then, Oakland now) win for having the most similar uniforms from the '80s to now ...

... they look almost exactly the same!

More nostalgia ...
