GettyTBQH, Christina's ensemble looks strangely similar to my first grade art project that I forced my mom to hang in her office.
4This leopard print delight
GettyChristina swore by this early aughts fashion rule: When it comes to leopard print, too much is never enough. We give her bonus points for the hot pink lace trim on her camisole, which is very 2000s of her.

17This cutout dress
Steve Granitz//Getty ImagesWe can't tell if it's the sparkly tiger print or the string peeking out from her hip that makes this dress so awesomely 2000s. Probably both, tbh.

GettyWho doesn't want to wear jeans that look like they were made from 1 million other pairs of jeans? #Recycling
20This low-cut romper
GettyFrom Christina's metallic bandeau top to her bedazzled belt sitting low on her hips, I'm willing to bet this wasn't the comfiest outfit to wear while sitting down.
