Sisters and reality TV stars Kim and Khloe Kardashian are doing a “who wore it better” showdown. Khloe has been spotted wearing the same keyhole dress that her older sister wore a year ago.

Khloe was photographed out and about in Australia on Tuesday. She flew down under to promote the Kardashian Kids clothing line that she owns with her sisters. She stepped out wearing an olive green body-hugging dress by Michael Costello. The mid-length dress has long sleeves and a cutout keyhole at the center of the bodice.

Eagle-eyed Kardashian-watchers were quick to note that Kim was seen in almost the exact same dress about a year ago. Us Weekly shared the recent photo of Khloe and a photo of Kim which was taken from Aug. 11, 2014. Although essentially the same, there are minute differences in the sisters’ dresses. Kim’s dress was in burgundy and her neckline was higher than Khloe’s. The older sister's dress was also slightly longer. The dress was first seen on Kim almost exactly a year ago when she stepped out with her BFF Jonathan Cheban in New York City.

The members of the Kardashian-Jenner clan have never shied away from wearing matching outfits or borrowing clothes from one another. In fact, even Caitlyn Jenner has gotten in on the act. She has recently been spotted wearing a flowy dress that was originally made for Kim. After Kim wore it on a family trip to Mexico, the dress was spotted on Caitlyn on her new docu-series “I Am Cait.” Incidentally, that dress was also made by designer Michael Costello.

In the show, Caitlyn also found out that she owns the same Tom Ford dress as her ex-wife Kris Jenner. In a short clip shared by E!, Caitlyn and Kim could be seen planning to go on a “who wore it better” showdown with Kris. The two girls had fun plotting a surprise meeting with Kris while both exes are wearing the same dress.
