The actress – best known for playing Nicky Wheatley in the ITV soap – was attending a special night honouring the NHS.
Kimberly, 36, stunned in a white ruched maxi dress as she attended the NHS Staff Awards at the M&S Bank Arena in Liverpool.
The TV star showed off her trim figure, while flashing major side boob in the daring low-cut frock.
Kimberly revealed her dress was second hand dress and cost just £27 from online retailers Mars The Label.
The Celebs Go Dating star wore her blonde tresses in a sleek ponytail and opted for subtle bronze make-up, with a pink lip for the outing.
The soap star accessorised with white see-through heels, a pair of sparkly dangling earrings and a white clutch bag.
She captioned the post: “A night of NHS. Honoured to present an award with the beautiful Ellie Leach wearing my second hand dress.”
Kimberly’s fans were stunned that she managed to grab this occasion dress for such a bargain.
One wrote: “Lovely pics as usual looks like had fab time at awards and dress looks amazing on you.”
Another posted: “You look like a movie star. Stunning.”
A third added: “Love this look. Miss you on our screens.”
Many Corrie fans will know Kimberly from her time on the cobbles.
The TV star first appeared in Corrie back in 2020 as Nicky, a Sєx worker who grew close to Daniel Osbourne.
After two years away she returned last year for another short stint.
Speaking exclusively to The Sun, Kimberly said: “People have definitely mixed up my character with me. Men think it’s really funny to approach me and say, ‘How much?’
“I am on dating apps and it comes up on there, too. I just unmatch them straight away.
“But I am thrilled that charities and Sєx workers have contacted me to say they like the way Nicky is portrayed because she is so realistic and the writers haven’t given her a drug or drink problem.
“She is just a feisty mum, doing it for her daughter — for survival. I am so proud to play her.
“I know plenty of people who work in the Sєx industry and on things like OnlyFans — it isn’t an unknown world to me and they are just normal people trying to get by. Fair play to them.”
