The 32-year-old reality star, who welcomed her daughter North West in June, showed off her hourglass figure in a tight PVC nude skirt that clung to her curves, teamed with a white top and nude heels.
Also visible was the gold 'Nori' necklace she has been wearing throughout her trip to the romantic French capital, in honour of her daughter.
Kanye kept her arm protectively wrapped around Kim as the couple enjoyed a date night at Costes restaurant. The 36-year-old rapper was casually dressed in ripped jeans, a grey knit V-neck jumper, brown boots and a gold chain.
Kim's attendance at Paris Fashion Week marks the first time she has been away from her baby daughter.
She arrived with Kanye on Saturday morning, leaving three-month-old Nori at home in Los Angeles.
"Kim was sad to say goodbye. This is the first time she's been away from the baby," an insider told usmagazine.com.
According to reports, the couple decided it would be "too dangerous" to bring their baby girl along on the visit.
"Kim really wanted to take Nori to Paris but Kanye insisted that it wasn't a good idea because of his issues with photographers," a source told RadarOnline.com. "He thought it was too dangerous."
Kanye was also keen to spend some time alone with Kim, and has been escorting her on date nights and to numerous fashion shows during their stay.
"Kanye has set up multiple meetings with Chanel, Celine and Givenchy to design a new post-pregnancy wardrobe for Kim," the inside added. "He thinks this is a prime opportunity for her to re-vamp her image."
