Just when we were getting too comfortable with her look, Christina switched it up on us and re-created her style towards a classier and vintage look.

Here, she pulls off a glam blue dress with feminine jewelry and back to her soft, blonde locks.

In 2007, staying true to her new image, she kept it classy in a skirt suit. But she would not be the same without her accessories: long necklace, a brooch, slouchy boots, tights, and the decade’s favorite Alexander McQueen skull scarf.

Christina Aguilera 2000s Style — Outfit Ideas:

Products: Pants – H&M, Bodysuit – Nordstrom, Belt – Nordstrom, Necklaces – River Island, Patches – Etsy

Here, we take a bit of a DIY approach to get Xtina’s dirrty look. You can personalize your own pair of military green cargo pants with various patches that speak to you.

Add a chained belt for the vintage look and wear a bodysuit underneath for a feminine flair. Lastly, layer a few necklaces to finish the look. There you have it, the perfect Christina Aguilera 2000s vibe.

I love this modern slip dress because it’s tailored at the waist and will accentuate your curves.

Pair the simple and sweet dress with a layered tassel necklace, black sandal pumps, and bright red lipstick for a night out.

What I love most about this outfit is that nothing matches, per se, and yet, Christina was still able to put it together so effortlessly. It’s all thanks to the color palette, which incorporates shades of red.

Black and leopard accents dress the whole look up. (How cute are these block heels?) Lastly, layer with some black tights, as Christina did, if the weather is chilly!
