28 Nostalgic Fashion Moments We Witnessed on The Hills and Laguna Beach

Because why decide between pants or shorts? Lauren Conrad certainly didn't while visiting TRL.

Neither did Kristin Cavallari.

Heidi Montag gave us preppy on top, party on the bottom?

Audrina Patridge was a fan of the camouflage skirt.

The smaller the skirt, the bigger the boots — right, Kristin?

Heidi showed off the going-out uniform in a barely there bandage dress and platform heels.

Kristin Cavallari proved the dress could get even sexier with cutouts.

Audrina Patridge had the uniform down while out in 2008.

Winter, spring, summer, or fall, this look always called for knee-high boots.

Heidi channeled Risky Business-meets-Wild Wild West.

The comfort of home, even on the red carpet.

We don't think Lauren's long dress needed leggings underneath, but that's the 2000s for you.

What would a party be in Laguna Beach without this look?

Again, Lauren proved a shiny satin top and boot-cut jeans are always appropriate.

How else would you dress up an LBD?

The barely there top was the natural choice to complete barely there shorts.

Kristen was also a fan of styling a strappy shirt with shorts and heels.

Lauren proved they're event-ready with the right accessories.

Bringing corsets to the red carpet.

Again and again.

The easiest way to dress up your underthings? Boots, of course!

Is there anything easier to throw on?

Add flats and a tote, and you're ready for whatever the day brings, without the risk of a tan line. That's crucial in Laguna Beach.

The skinny scarf and the newspaper boy hat? A total 2000s vibe.

We're not sure who told Jason Whaler he had to stay this color-coordinated.

Not even indoors.

It's the blazer that's perfect for beach-party casual.

Like the tube dress, though often worn with your favorite flares. Just throw it on and go.
