The all denim everything trend? Ain't goin' anywhere—says Miley. For Wednesday's MTV Unplugged performance, she rocked an Ashish look made up of sparkling denim pants (in the super-baggy silhouette she's been loving this year), an oversized denim shirt and matching bikini top. Now that was a TLC throwback. Last night, she stopped by Jay Leno (where she gossiped about Biebs' legal drama, FYI), and had another jean-on-jean moment rad enough to make Britney and Justin blush. What can we learn? Well, you can leave the denim bikini at home and still up your look with a blingy belt or sparkly purse. Boom! It's a party in the USA.
