Our staple style stars have been stepping out on two ends of the sartorial spectrum: either in bold fall colors or wearing bright so-not-just-for-summer whites.
Here's a rundown of our favorite looks of the week:
Reese Witherspoon attended Elle's 20th Annual Women in Hollywood Celebration in Los Angeles sporting a tangerine-hued Calvin Klein Collection frock with nude ankle-strap heels.
Also at the Elle soiree, British babe Ashley Madekwe wowed in a white pinstripe Thakoon dress, gold Saint Laurent sandals and matching Jimmy Choo clutch.
Can Lupita Nyong'o do any wrong? The 12 Years a Slave actress took to the red carpet in yet another winning look at the 17th Annual Hollywood Film Awards in a marigold J. Mendel gown paired with Monique Pean jewelry and a Judith Leiber clutch.
Hot mama Jessica Alba went for white in a Wes Gordon flare dress and cap-toe Jerome C. Rousseau pumps at Who What Wear and Cadillac's 50 Most Fashionable Women of 2013 event in West Hollywood.
And finally, who can resist a sheer skirt? Sophia Bush sported a sexy Escada pre-fall 2013 gown with metallic gray beading and high-low hem at the Pencils of Promise Gala in New York City.
