Style Radar: Faboo or Faux Pas? Girls (Still) Just Wanna Have Fun!

With not too many red carpet events Tuesday night, young starlets channeled 80s pop princesses, while middle-aged A-listers opted for soft and demure conservative sophistication.

Born in '93, Lilo's little sister Ali made like Madonna in her "Holiday" days, teaming tie-dyed leggings with a black zip-up vest and florescent orange retro Nike dunks at a Nylon and Nike event in NYC.

In London, fashion-challenged OC alum Mischa Barton stepped out in a jailbird Charlie Chaplin getup that had her puttin' on the ritz, albeit in all the wrong ways! Also in The Big City, Lily Allen walked like an Egyptian; well, not really, but the 24-year-old party animal did rocker-chic right, pairing cobwebbed leggings with a cropped sequin vest and a groovy, but very L.A. glam band.

Back in the City of Angels, Khloe Kardashian brought the Miami Vice style, hitting up a Naven and Boulee event in Hollywood decked out in a high-waisted, hot-pink mini with peep-toe Giuseppe Zanotti booties.

Back in 2009, Hollywood Mama Jennifer Garner strolled in Brentwood in a conservative cream ensemble, and Renee Zellweger stuck to the earth tones donning a khaki trench jacket for her dinner date in NYC.
