1. Bell Bottoms

'70s Version:

21st Century Version:

Fun fact: Bell bottoms originated in the Navy because they could easily roll the hem up to avoid getting wet.

Target with a bold throwback, the printed flare pant.

Express with a classic denim mid-rise jean (pictured above).

21st Century Version:

Kohl's. See especially these gorgeous ones by LC Lauren Conrad (including the one above).

3. High Waisted Skirts

21st Century Version:

(This photo has an added '70s trend of a colorful sweater. The '70s went through a big sweater phase.)

Find them today at:

Modcloth. They have a host of cute skirts, most of them high rise (including the one featured above).

4. Birkenstock

'70s Version:

21st Century Version:

Fun fact: Birkenstocks first came about in 1774 by German Johann Birkenstock. That means that they've been in business for 242 years!

The Birkenstock website (which sells the ones pictured above).

Cheaper options include these classic ones from American Eagle.

5. Jumpsuits

'70s Version:

21st Century Version:

(The one above follows the '70s trend well because it chooses a uniform color. The '70s liked their pants colorful and especially loved pastels.)

Find them today at:

Forever 21. They have many different options, ranging from the throwback pictured above to floral prints to denim!

Target also has a wide variety of jumpsuits.

6. Platform Shoes

'70s Version:

21st Century Version:

Fun fact: Platforms were originally worn by Greek actors so that the audience could see them better on the stage. The taller the platform, the more important the actor.

Find them today at:

Dillards. The Gianni Bini line has a big seventies flair, like the one above, which nods to the clog, another important shoe of the '70s!

7. Fringe

70s Version:

21st Century Version:

Find them today at:

Francesca's. They have a fun selection of kimonos (another trend from the '70s), many with fringe, like the one above.

American Eagle. They have found a way to put fringe on everything, especially shoes!

With all of these '70s trends coming back, it's no wonder the 21st Century fashion scene feels a bit more groovy. The real question is, which trend will you buy into first? I call dibs on bell bottoms!
