These before-and-after photos show how much teen fashion has changed in the past decade

Abercrombie & Fitch

Teen retail has changed a lot in the past decade.

In 2006, teens loved brands like Abercrombie & Fitch, American Eagle & Aeropostale.

There was a distinct teen look — on with logos and brand names.

Now teens opt for simpler looks ... or looks that they can share on Instagram.

See how teen apparel has changed in 10 years.

First, let's go back to the 2000s. Who could forget Abercrombie & Fitch's shirtless models. Note the woman in a semi-compromised position wearing low-rise jeans and a white camisole — a faceless trend.

2006 was the year that former CEO Mike Jeffries told Salon that Abercrombie supposed to be for the "cool kids." This, apparently, was a cool kid, wearing the necessary in-style fringed denim skirt.

Aeropostale was a mall staple, telling that world that couples who dressed alike stayed (in monochrome outfits completed with denim) stayed together.
