The Kardashian clan may be best known for their glitz and glamour but that's far from what's on show in Kim Kardashian 's latest throwback photo.
The SKIMs founder, 40, took to social media on Tuesday to share an adorable childhood snap of her and older sister Kourtney, 42.
The two then-toddlers can be seen wearing Groucho Marx costume masks and disguised in funny faces in the hilarious pose.
In it, Kourtney has her arm around little sis Kim who is wearing her signature bubblegum pink even as a youngster.
Looking through their "disguises," the pair have matching hairstyles and nearly identical features making it difficult to tell who is who.
Kim captioned the snap: "Baby Kim & Baby Kourtney in disguise."

The duo's younger sister Khloe, 37, certainly appreciated the throwback as she commented on the Instagram post: "OMG the cutest."
And fans of the stars seemingly agreed.
One wrote on Twitter : "Our own little Pink Panther! The beginnings of a true sleuth! Awesome memories I’m sure! Ever blessed my love."
Another commented: "Ahh the memories... .you still got those disguises right?"
And a third put: "Y'all look so adorable."
Many others filled the comment sections on both Instagram and Twitter with an array of love heart emojis.
The throwback comes as Kim enjoys a trip in Rome. The reality TV star was snapped taking in the hot tourist attractions, including the colosseum.
The Keeping Up With The Kardashians star posted regular videos and pictures of her private tour with her 231 million Instagram followers.
She posted a video where a tour guide can be heard explaining the history of the landmark, talking about gladiatorial combat.

Kim was seen to be enjoying the trip with hair director Chris Appleton and makeup artist Mario Dedivanovic as the trio posed for pics in the glorious Italian sunshine.
The trip follows Kim denial several weeks ago of any involvement in the illegal smuggling of an Ancient Roman statue out of Italy.
Representatives for Kim insist she had nothing to do with it, after reports a $750,000 shipment in her name was seized by US custom officials in 2016.
