Best Looks of the Week: Gwen Stefani, Halle Berry and Others Embrace Fall Trends

Several stars stepped up their fashion A-game this week, and we couldn't be more pleased. From coast to coast, we saw a number of incredible looks that inspired a hankering for more fall trends and stylish celebs to ogle.

Lace, leather, tuxedos and winter white all stood out as major themes this week. Halle Berry dazzled in silver lace Dolce & Gabbana, while Rosie Huntington-Whiteley left little to the imagination in a seductive sheer lace Jason Wu cocktail dress. Meanwhile, Alexa Chung looked like a stylish schoolgirl as she toasted the new Versace store opening in New York clad in an oxblood leather skirt look paired with black cutout loafers.

And for daytime, Victoria Beckham attended the CFDA/Vogue Fashion Fund luncheon in L.A. wearing a fresh all-white ensemble with peep-toe ankle booties and her trademark oversize shades.

Gwen Stefani was the queen of cool at the same function, clad in a chic black and white tuxedo look by Calvin Klein Collection. An exposed black bra and a pop of vibrant red lipstick added undeniable sex appeal. 

But for an overall winner, we have to hand it to Stefani, who scores big for her effortless glam look. Who do you think looked best this week?
