The streets of Paris, France have transformed into high-fashion catwalks as the City of Lights welcomes several A-list celebrities for Paris Fashion Week. And while some stars are fitting right in with the well-dressed crowds in the front row at this season's hottest runway shows, others are standing out for the wrong reasons.

BEST DRESSED: Jennifer Hudson, 30, worked pin-straight strands and a tight black dress while sitting front row at Givenchy Oct. 3, while Salma Hayek proved that not even an ankle brace could prevent her from looking chic at the Yves Saint Laurent show Oct. 3. The 45-year-old actress donned a beige leather mini that matched her nude bandage wrapped around her right leg.

WORST DESSED: Emily Blunt, 28, stepped out in a jewel-toned ensemble that looked more appropriate for Mardi Gras as opposed to the ultra-chic Yves Saint Laurent runway show Oct. 3, where she sported a shiny purple blouse and a glimmering bronze reptile print knee-length skirt.

The day before, Olivia Wilde, 27, covered up for the Tod's party in a vintage, red and white lace floor-length Oscar de la Renta gown, which she paired with black sandals adorned with huge blooms.
