This week brought the return of a few favorite fashionistas.

Natalie Portman hit her first event since the 2013 Oscars. Naturally, the Dior spokesmodel opted for an orange frock by the French brand for her red carpet comeback.

Another gal that likes to keep a low profile, Kristen Wiig, stepped out in Paris at the Imogene premiere, looking ultra chic in a Prabal Gurung dress.

Then there were those leading ladies who gussied up while supporting their other halves. Like Rosie Huntington-Whiteley who wowed at longtime love Jason Statham's Hummingbird premiere in London. The blond bombshell chose an Emilio Pucci mini and matching Casadei pumps, which accented her long legs.

Also looking stunning while at her man's side, first lady Michelle Obama wore a lovely Carolina Herrera dress while visiting Berlin.

For the best on-trend ensomble, Shay Mitchell takes top prize. The Pretty Little Liars star pulled off two-trends in one look by donning a printed Clover Canyon crop top and skirt combo.
