The Best Dressed Stars This Week: 8/23/13

Lily Collins secured her status as the current "it girl" of fashion in three standout ensembles, while Sofia Vergara transitioned into fall with tights, and Zhang Ziyi sizzled in stripes—check out the chicest celeb looks this week.

Lily Collins

This last week has pretty much been "The Lily Show" due to the actress' whirlwind Mortal Instruments press tour featuring one stylish outfit after the next. This magenta Osman number though...TOPS my list of faves.

Sofia Vergara

Reminding us that fall is just around the corner, Sofia paired her Michael Kors black and grape flirt dress with tights to the 65th Primetime Emmy Awards.

Julie Bowen

Julie Bowen looked HOT in this burgundy Catherine Deane dress at the Academy Of Television Arts & Sciences Cocktail Reception To Celebrate The 65th Primetime Emmy Awards. The actress accessorized with Monique Lhuillier shoes, a Judith Leiber clutch, and Doves by Doron Paloma jewelry.

Maria Sharapova

Maria attended the launch of her new accessories line, Sugarpova in a David Koma dress, Rupert Sanderson shoes, a Graziela Gems ring, and Sugarpova earrings.

Analeigh Tipton

I loved Analeigh Tipton's Alberta Ferretti black, floral, embroidered dress at the premiere of The Grandmaster—so stunning!

Rosamund Pike

Also killing it in a LBD was Rosamund Pike, who wore Marios Schwab Resort to the premiere of her film, World’s End.

Taylor Swift

Tay kept it cute in a Contrarian New York strawberry-print dress and Lauren Merkin 'Stevie' equestrian bag out and about in NYC. Every gal needs a whimsical sundress for summer, don't cha think?

Zhang Ziyi

Zhang's bold striped skirt and cropped black jacket just work—refreshing and fun.
