All four ladies never look anything short of fabulous and they've now rocked exactly the same cute crop top and skirt combo, but we can't decide who wore it best...
The two-piece in question is from Miss Selfridge, with the top priced at £32 and the skirt at £39. We're totally in love with the sunny summery outfit, and it looks like everyone else is too as it's already sold out online. Boo!
Mols was way ahead of the pack when she wore hers last month (10 March) while signing copies of The Saturdays' new single, accompanied by her sweet pup Alfie.
The songstress rocked her usual golden tousled curls and flicked liner, skipping the accessories and flaunting a pale pink mani.
And the adorable outfit also has the Chelsea seal of approval from Rosie, as she posed in the ensemble while shooting for her fashion blog on Tuesday (1 April).
Rosie also wore her hair in loose curls, adding a touch of interest with a chain necklace by Joomi and swoon-worthy blue studded heels by Valentino.
Proving this getup really is the two-piece du jour, Essex lass Sam then stepped out in it while heading to The May Fair Hotel in London yesterday (2 April).
Sam actually went for a similar look to Rosie by rocking bright blue heels, tonging her ombre locks into glamorous Hollywood waves.
She ditched the jewellery, simply teaming her twin set with a sunkissed glow and a mega-watt smile!
And it's not just these three who have sported the look... Zoe is in on the action too.
Posing in front of a glistening blue swimming pool in Dubai last month (29 March), Zoe looked every inch the fashionista with a statement gold cuff and red heels by River Island.
There's no way we can choose a winner for this style-off, they all looked incredible!
