Don't worry, not her own Christening dress, Operation Transformation hasn't gone that extreme...yet. Nope, it was the dress that leader Marie had bought for her daughter's Christening, only to realise that it didn't fit her.

On tonight's show however, viewers will see host Kathryn Thomas pay a visit to Marie to go through her wardrobe and get rid of all her clothes that are now too big, and while there, Kathryn encouraged her to try on the infamous dress.

And well, it fits!

Fair play to her. 

Operation Transformation airs Wednesdays and Thursdays at 8.30pm on RTÉ One.
