The devil's in the details, and this week's best dressed were all too keen to that fact when they hit the red carpet. Starting the week off strong, Rosie Huntington-Whiteley ensured we pay close attention to every angle of her Emilio Pucci gown when she spun around to reveal its lacy back.
And while stars like Taylor Swift , Jennifer Lopez , and Alexa Chung relied on strong color choices to make their dresses truly stand out, others like Kristen Bell  and Kim Kardashian  knew sometimes a strong silhouette is all it takes. So what makes this week's best dressed stars so darn special? You'll have to get a closer look to find out!
