Jet-setter and trend-setter?

Sporting a pair of black and white optical illusion trousers, a top knot ‘do, and a black blouse with sheer slits in the sides, TV star Kim Kardashian was tres chic as she traveled back from Down Under to Los Angeles, Calif. on Friday.

Of course, the ensemble wasn’t complete without  designer shades, a tote, and sky-high stilettos.

What was Kardashian doing all the way in Australia?

The beau of rapper  Kanye West was on a business trip, promoting her QuickTrim weight-loss product while her sisters Khloe and Kourtney were off in Miami, looking for a new DASH Miami boutique.

Not to fret — Kardashian has reunited with her sisters, tweeting “Happy to be back in Miami” on Saturday.

And she’s back to spending  quality time with her boyfriend, gushing on Monday:
