Riff Raff Katy Perry Denim Outfits - P 2014

Britney Spears and Justin Timberlake a la the 2001 American Music Awards, anyone?

Who knew Katy Perry was such a Britney Spears fan?

She and rapper Riff Raff showed up on the VMAs red carpet on Sunday in head-to-toe matching patchwork denim — a purposeful tribute to Britney Spears and Justin Timberlake's 2001 American Music Awards ensemble.

Her strapless, rhinestone-studded modern-day iteration was designed by Versace (see telltale slit), and she paired it with a choker, belt and patchwork bag and pumps. Perry's date may have been missing Timberlake’s denim cowboy hat but he sported a coordinating suit along with a shiny silver top, lots of bling and pink cornrows.

She Tweeted about the outfit before hitting the carpet, saying: "I must admit my outfit is a result of my love for nostalgia and my Tumblr addiction." We're guessing Perry bestie and stylist Johnny Wujek would agree. 

Baby one more time, indeed.
