Christina Aguilera In Concert As Part Of The GP Masters

Christina Aguilera turns 33 today, and to celebrate, we thought we’d chart out her style evolution over the years.

I love Christina, and still likely know every word to “Genie in A Bottle.” Actually, I definitely do, which begs the question of why did my parents let me listen to that? It was basically smut. Fun, upbeat, dancy smut. I loved every minute.

I spent literally hours going through Aguilera’s many red carpet and performance outfits since 1999, and unfortunately things haven’t always (or ever) been great sartorially for my girl Christina. In fact, it seems like her style might be inversely proportional to her powerhouse singing voice, leaving her fashion evolution as a history of disaster.

The late 90s to early 00s were prime Christina time–it gave us her self titled debut album featuring “What A Girl Wants” and “Come On Over (All I Want Is You),” and “Stripped,” which I remember for “Fighter” and “Beautiful.” It also gave us the following fantastic time capsule of turn-of-the-century fashion:

We start in 1999, with Aguilera in her Genie In A Bottle Phase. She was 19!

I’m not sure if I should make a bra joke, blazer joke, or eyeshadow joke.

Those pinstriped, lace up pants seem fun.

This is classic Xtina. We’re getting into her love affair with hats and scarves–she even used a scarf as a boob holder here!

Okay. This is the most Christina Aguilera look of all time. Garish boots, wide legged capris, belly top, scarf, and perfectly askew hat. Why is this not on every album cover of her career?

Hats and capris.

So this could be something. At least it doesn’t involve a hat. Elegant Vegas showgirl, perhaps?

There was a real tidal change around 2005. Aguilera switched things up drastically with a major reduction in self tanner, giving us a human-hued person instead of a deep orange cartoon.

Christina started her excellent love affair with beaded, Prohibition-inspired gowns around this time, but took a step back in the self tanner department.

I hope that scarf kept her warm.

2008 MTV Video Music Awards - Arrivals

Aguilera’s Black Swan-esque eye makeup, blunt bangs, and vampy dress are rotally on point, but it’d be great if she’d give her hair a day off from the flattening iron.

If Beyoncé wore this today, nobody would bat an eyelash.

2008 American Music Awards - Red Carpet

This is Christina Aguilera’s best look up until this point, and it only took her until 2008. The Bettie Page bangs and dark red lipstick are perfect. I can deal with the flowers on the straps of the gown.

And a giant step back for Christina but a leap forward for pointless scarf visibility.

It’s simple and clean, if not boring.

Now we’ll enter The Modern Era, starting in 2010.

Aguilera surprised the whole world with this polished, clean, and elegant look. In fact, this might be her best outift of all time. Her hair should always be cut in a blunt bob.

As it turns out, progress is slow. I love her hair and make up, but what is this goth Christmas tree?

It sort of reminds me of the dress Michelle Obama wore when Barack Obama made his victory speech in 2008, but unappealing.

I love this color on her, but she’s veering back into Country Music Award territory with that hair.

68th Annual Golden Globe Awards - Arrivals

And now that her hair’s simpler, I hate the dress. Okay I give up. I’m sorry. She can’t win. I just want the best for you, Christina.

Look I gotta give it to her. Even in lavender ombre, she look sexy as all hell.

I love the top and it’s interesting to see her in pants that reach her ankles. I am, however, beginning to wonder if Aguilera has an obsession with visible flies. I’ve never not seen the exact apparatus she uses to put her pants on.

2013 American Music Awards - Arrivals

And she’ll close out 2013 with this almost elegant white gown, which is a little shiny to really work. But my god. We’ve come a long way.

Happy birthday, Christina!
