Forget billboards! The Kardashians (as many as there are) are walking advertisements for their Kardashian Kollection for Sears.

Among many other pieces from the "kollection," Kim and Kourtney (both of whom have been making rounds during Mercedes-Benz Fashion week along with little sis Kylie Jenner) have both been spotted wearing the Lace Button Up Shirt With Oversized Neck Bow and Lace Trim Georgette Skirt.

While Kourtney opted for the Vintage Apricot shade, and Kim for Black, both ladies looked adorable in the pretty pairing. (Kim has also been spotted wearing the skirt in the Vintage Apricot shade with a black top).

Who looked lovelier in these lace Kardashian Kollection separates? Weigh in below!
