Jessica Biel's Lilac Jumpsuit, Olivia Culpo's Sheer Perfection & More Best Dressed Stars of the Week

From streetwear to red carpet glamour, these are the stars who slayed the fashion game during the week of Nov. 12.

It's all in the details. Margot Robbie perfectly paired her velvet gown with a whimsical feathered jacket. Jessica Biel completed her pastel look with a lavender headband and Rachel Bilson added a touch of sparkle with gold dangling earrings.

An elegant or understated ensemble can be toned down or dressed up with the right amount of bling, a staple shoe or the perfect shade of lipstick. Or maybe, as was the case with Lisa Bonet, a stunning date like her new hubby, Jason Momoa, can make for some great arm candy. This week, accessories were among the staple pieces that added a fashion-forward punch to celebrities' outfits.

These stars -- and their handy stylists -- made all the correct choices and slayed the fashion game for the week of Nov. 12.

ET has all the details on Hollywood's best dressed -- and where you can get their looks!
