All three girls have been snapped wearing the navy blue jumpsuit with zip pocket detailing.
Trend-setting Mollie wore hers first - back in August 2013 - when she attended the We're The Millers film premiere.
She put her own spin on the look, adding a black waist belt. Glossy hair, a metallic clutch and simple black courts topped it off.
Nicole worked the same outfit just a few weeks later as she posed at an X Factor press launch held at London's Mayfair Hotel.
She braved the colour clash trend, mixing her get-up with red court shoes, a yellow mani and sunshine yellow shades!
And just last week, Alesha Dixon followed in Mollie and Nicole's fashion footsteps.
She showcased her post-baby body as the new Britain's Got Talent auditions kicked off in Belfast.
The judge paired hers with a jacket draped over her shoulders and nude patent heels.
Loving the girls' look? Their jumpsuit is from Three Floor - the clothing label that celebs just can't get enough of!
At £145, it's pretty pricey but if Nicole, Mollie and Alesha are anything to go by, it's a multi-tasking piece that will work everywhere!
