Kim KW was first to rock the look when she stepped out in an under-the-sea ensemble for Halloween in 2012.
She swapped her dark locks for a platinum blonde wig, adding pearl necklaces and plenty of embellishment to maintain her trademark Kardashian bling factor.
The Only Way is Essex's Ferne McCann took things further with her creation for Sam Faiers' birthday party earlier this year.
Adding dark lipstick and red-coloured tresses, Ferne channeled The Little Mermaid's Ariel with a vampy spin.
Both starlets worked the look well so it's not surprising Ferne's co-star Georgia donned a similar outfit for the spooky season.
The Essex girl put her own twist on the look with a white bikini top that showed off her toned tum. And top marks for going all out with the face paint!
Kim, Ferne, Georgia and even Myleene Klass (check out her fishy-inspired holiday snap!)... it looks like the whole of celebville's getting in on the sea siren action!
