Nadia Sawalha sports black 'bin bag' bikini in Kim Kardashian imitation pic
The 57-year-old British actress and Loose Women panelist, whose father is Jordanian-British actor Nadim Sawalha, included a challenge for her followers.
"Can anyone guess what THREE 'textiles' my brilliant stylist @thedinasawalha [her sister] used to recreate @kimkardashian stunning @sportsillustrated look?" she asked.
"Clues are… Woof woof; Stay fresh; This will keep anything in place!
The image Sawalha posted to Instagram was split down the middle.
On the left side, Kim Kardashian sits atop what appears to be a board in a pool, while on the right, Sawalha is perched on a board of her own set on a table.
A dog is in the bottom left-hand corner of the shot.
Instagram users found the post hilarious, with one saying: "Oh Nadia you really need to bring your own bikini range out, because that does not look hand made."
Others took guesses at the materials used.
"Poo bags and gaffa tape?!" one asked.
"It's anyone's guess. Love how you rock these better than Kim K," another said, including laughing emojis in their message.
One Instagrammer was amused that Sawalha had managed to find a motorcycle helmet like the one Kardashian was holding in her photo.
"Where the hell did you get the helmet?" the user said, adding that it was "BLOODY BRILLIANT".
