Famous fashion favourites stepped out in an array of outfits this week, and we're here to break it all down for you.
In case you were wondering, Jennifer Connelly's still got it, and she proved that at the Zurich Film Festival this week.
For a premiere of her film "American Pastoral," the 45-year-old actress worked the red carpet in a custom Louis Vuitton dress featuring a ruffled T-shirt-style bodice and an extreme thigh-high slit.
Meanwhile, Rihanna was just her stylish self, looking like a badgal version of Marie Antoinette at her Fenty x Puma by Rihanna show in Paris.
But our fave fashion moment of the week had to be when Catherine, the Duchess of Cambridge, donned a coat by Canadian label Sentaler, marking a proud moment for our country's fashion industry.
Check out the rest of our best dressed picks of the week below!
Best Dressed: Week Of Sept. 25, 2016
Jennifer Connelly In Louis Vuitton(01 of47)
In case you thought otherwise, Jennifer Connelly's still got it. The actress looked sexy, yet stylish in her custom Louis Vuitton dress with an Angelina Jolie-esque thigh-high slit. We love the juxtaposition between the flash of skin and the more conservative, girly ruffled top. Also, can we just all agree Connelly is simply ageless? (credit:Andreas Rentz via Getty Images)
Lupita Nyong'o In Monse(02 of47)
Yes, we love Lupita Nyong'o in colour, but black and white looks just as good, especially when the colours are mixed in with contrasting patterns. (credit:Ray Tamarra via Getty Images)

Mandy Moore's comeback is in full force, and she's got the wardrobe and hair to go with it. At the HearstLive Launch this week, the "This Is Us" actress sported a velvet gown with a deep V-neck.

Kate Middleton In Sentaler(11 of47)
Possibly our fave fashion moment of the week was when Catherine, Duchess of Cambridge, donned Canadian label Sentaler during her royal tour of Canada with Prince William.

Lupita Nyong'o wowed us at the premiere of "Queen of Katwe" at the Toronto International Film Festival, and it looks like her style streak for the film's press tour is going strong. At the movie's premiere in Hollywood this week, Lupita stunned in a lavender Ellie Saab gown complete with bold pops of colour along the edges of the bodice and the waist. And of course, her head wrap was the perfect finishing touch. (credit:Albert L. Ortega via Getty Images)
