Rachael Leigh Cook, Rosario Dawson and Tara Reid

The tops of all three of these dresses are VERY 2001. None of us wore sleeves to formal events at the turn of the century. As a Halter Top Lover, it was a golden time for me.

Rosario Dawson

At some point in the evening, Rosario definitely fell off those shoes.

Tara Reid

How WHOLESOME and cute Tara Reid looks here.

Tara Reid and Carson Daly

I...forgot to get a photo showing Carson Daly's face. He looked like Young Carson Daly. (They were engaged at this point.)

Alan Cumming

Alan Cumming is great in this movie and looks slightly sweaty at its premiere. Who wasn't?!?!

Alan Cumming and Jennifer Jason-Leigh

Jennifer Jason-Leigh is ALSO excellent in this movie and I feel confident that I actually owned that purse. (It was Kate Spade. I wish I still had it.) (Wait, I lied. She's not in this movie, that's Parker Posey. Maybe she just loves ears!)

Kathy Najimy

Get you a Hollywood friend who is this supportive! (Kathy also looks very cute here.)

Tia and Tamera Mowry

I told you we spent a lot of time trying Sleeveless Configurations!

Shannon Elizabeth

This has a real Alanis Morissette Energy.

Kiefer Sutherland and his daughter Sarah

It's cute to see Celeb Dads bring their daughter to this. (Fun fact: Sarah grew up to be an actress and played Selena's daughter Catherine in Veep. I did not know that until JUST now. She was very good in that part!) (Yes, these were the headbands I was shilling.)

Anthony Stewart Head with his daughters Daisy and Emily

And Giles brought his daughters, who are also so cute! (They're ALSO both working actresses right now! Daisy was on the third season of Harlots and Emily was on The Inbetweeners.)

Frankie Muniz and Amanda Bynes

Amanda Bynes also brought her son, Frankie Muniz! (No, they were dating at the time.) (Actually I totally made that up.) (They're actually just long-time friends.)

Lindsay Sloane

I feel like Lindsay Sloane, whom I love, could dig this all out and add some chunky jewelry and become a rich hippie who lives in New Mexico.

Shar Jackson

For a second, I wondered if Shar was in this movie and I just forgot, but she was not. (She was, of course, on Moesha and a bunch of other stuff and you may also remember her from being Kevin Federline's veerrrry recent ex when he ran off with Britney. They were always very amicable, mostly I think because both K Fed and Shar are good parents.)

Gabriel Mann

I totally forgot he's in this movie. And I did not realize until just now that he's in the Batwoman TV series. Good for you, Gabriel Mann! You were arguably the best part of Revenge.

Kenny "Babyface" Edmonds and Tracey Edmonds

TRACEY! This outfit could be in the Smithsonian, under "THE EARLY AUGHTS."

Jesse Bradford

Lots of Jesse Bradford content on here lately. (This hat was a profoundly 2001 choice.)

Kerr Smith

Also lots of Kerr Smith content!

Angelica Bridges and Brandon Davis

The fact that Brandon Davis -- he of the famous Lindsay Lohan "Firecrotch" rant and boy celebutante extraordinaire of the aughts -- is holding a cigarette here is amazing. I sat next to him at the movies once and he came in late, kept leaving to get food, ate like six different movie treats, and at one point I looked over and he had lifted up his hoodie and was pinching a bare-skin fat roll on his stomach. Whomst amongst has not done so?

Ryan Reynolds

Look at this baby face.

Put on Your Ears for the 2001 Premiere of Josie and the Pussycats

An underrated gem!
