For the Operation Transformation final, you go big or you go home, and that applies to the presenters as well as the fabulous five leaders

Last night saw the fierce five strut their stuff down the OT catwalk, but they were in glamorous company as presenter Kathryn Thomas was on hand to celebrate with them in her glad rags. 

And what a look she pulled out. The presenter has been stunning with her outfits week in, week out, choosing Irish brands where she can and giving us a much-needed dose of glam during the week. Not one for wasting a chance to get dressed up, Kathryn saved her best look for last.

The star chose a look of "powder blue tulle loveliness from the Uber talented Simone Rocha", she wrote on Instagram, adding that she bought her stunning gúna from Havana Boutique in Dublin's Donnybrook. "Nikki and the girls in the shop are amazing and always go the extra mile for their customers. Delighted to support Irish designers and Irish retail."

Simone Rocha is known for her bold and feminine designs that marry romantic silhouettes with contemporary and unexpected design details, and this piece is a true summation of everything she excels at. 

The dress features voluminous puff sleeves in sheer tulle, a full A-line skirt and a delicate sweetheart neckline. The princess vibes of the dress were only enhanced by its intricate embellishments in contrasting red and white. 

She added a further bold touch to her otherwise incredibly feminine outfit by choosing a pair of black platform Mary Janes from ASOS that elongated her legs and kept the look fresh and modern. To this she added a smattering of silver rings for some sparkle. 

As for her makeup, it was one of her most glam yet. Kathryn went for a striking red lip to match her dress, with sharp glowy contour and smokey eyes adding a sultry note to her look. 

Her hair was styled in sleek and natural waves that perfectly framed her face and didn't compete too much with the dazzling ensemble.
