On tonight's episode of Operation Transformation on RTÉ One at 8:30pm, host Kathryn Thomas visits part-time hairdresser and mother of two Marie Grace to go through her wardrobe and gives her a fashion boost.

The two women decide to throw out any old clothes that are too big for her now. Kathryn suggests that the Tipperary leader should try on the dress she bought for her daughter's christening but couldn't fit into on the day.

The results are fabulous and Kathryn is quick to praise Marie:

 "You look so blood hot. Where is the belly gone? You're just boobs and bum, it's amazing! So how does it feel to be standing in THE dress?"

Marie responds: "I'd have to say I'm proud of myself."

Also on tonight's episode, Seán Daly is presented with a rather alternative gift from his work colleague Marissa. She presents him with a bag of potatoes to represent how much weight he has lost so far. However, the gift isn't received as well as Marissa had hoped.
