From glamorous red carpet events to the stylish streets of Paris, Hollywood's famous fashionistas stepped out this week in their favorite couture creations.
Kris and Kylie Jenner stunned in matching monochromatic black-and-white ensembles, while the usually-glamorous Lupita NYong'o failed to impress in a frumpy Maison Margiela frock in the City of Light.
Nicky Hilton raised some eyebrows at Paris Fashion Week, when she gave photographers a peek at her underbutt as she headed up the stairs in a white mini with sheer paneling at the Versace show.
Another star to show a bit too much skin was Chrissy Teigen, who had a double nip slip in a see-through gown at the Vogue Paris Foundation Gala.
Something tells us Anna Wintour might not be too pleased with this racy look.
