The 21-year-old wore a light chambray shirt with dark denim skinny jeans and denim blue ankle-strap stilettos designed by Saint Laurent. She gave an ode to Leno's infamous outfit. Leno wears a denim shirt and denim jeans when he's not working the "Tonight Show."
Cyrus also wore denim on denim during her MTV "Unplugged" special on Jan. 29. That time, she wore a sparkly denim jacket with a bikini top and baggy and ripped jeans.
Some would say that her looks take them back to 2001 MTV American Music Awards. That's when famous couple Britney Spears and Justin Timberlake wore matching denim-on-denim outfits.
Cyrus even admitted that she wanted a boyfriend that would wear denim on denim with her. She mentioned this tidbit after shortly breaking up with fiance Liam Hemsworth in September.
Miley Cyrus hasn't met her Justin Timberlake yet. She will have to settle on wearing denim on denim by herself.
