Kathryn Thomas dressed to a theme for last night's episode of Operation Transformation, and shared her own secret for looking so polished on the show. 

The presenter is known for her bold and colourful sense of style, and her dazzling wedding dress – featuring an open back and dramatic draping – divided the nation in what could only be a good way.

A fan of fierce prints, striking silhouettes and Irish designs wherever she can get them, the OT host has been nailing her looks on the newest season, and last night's was another blinder. 

Stepping out at the weigh in, Thomas wore Irish brand Lennon and Courtney, the celebrated range by Sonya Lennon and Brendan Courtney. Known for their retro patterns, vivid colours and sleek tailoring, it's no wonder Thomas chose them.

She went for the New Direction Knot Dress from their latest collection, a dazzling design covered in blue and black diagonal stripes. Featuring a high turtleneck and long cuffs in contrasting black, voluminous sleeves and a fitted pencil skirt design, it was equal parts retro and modern. 

She styled the dress with a pair of nude strappy sandals and wore her short blonde hair poker straight. She finished the outfit with a neutral smokey eye with lashings of feline eyeliner and a nude lipstick. 

Posting on Instagram, she wrote "So comfortable", adding that the design team "just keep raising the bar".

She also shared a little behind-the-scenes secret to keeping her outfits looking polished. She wrote: "Underneath, Shape wear by Irish company" ATIR. "They're UNREAL, for holding you in in all the right places.... check 'em out."

Specialising in shapewear and leggings, they're the go-to for many presenters and Irish celebrities, and we're loving how much Thomas is supporting Irish businesses. 

Her outfit pic was flooded with comments from her famous friends, with Anna Geary commenting "Gorge". The dress seems to be already sold out, but keep and eye out if you want to recreate this bold look.
