She's become almost as known for her dazzling turns on the red carpet as for her now-iconic role on Bridgerton, and Nicola Coughlan isn't slowing down when it comes to fashion.

The Galway native consistently turns heads with her ensembles, both on and off the red carpet, and has perfected her personal style. The star is known for her bright colours, avant garde silhouettes and details that marry feminine romance and edge.

The Derry Girls star's latest look is no different, as she took part in a campaign to mark 150 years of Tiffany & Co, as she celebrated with London department store Harrods by turning their lights blue for the next month.

Posting on Instagram, Coughlan wrote: "Tiffany & Co. and Harrods are both such iconic institutions, and so it is a real honour to partner with them to light up all 7,500 lights at Harrods Tiffany Blue, a magical night."

For the glamorous occasion, Coughlan wore a fittingly glamorous ensemble, stepping out in a diaphanous baby blue cocktail dress in a shade similar to that of the iconic jewellery brand.

She wore by Selezza London, known for their capsule collections that combine bright colours, modern silhouettes and surprisingly textures.

She wore the Noelle Tulle Top, a pleated off-the-shoulder cropped top in a flirty ruffled fabric that comes in a range of colours. She paired this with the matching Livia Tulle Midi Skirt, which features a voluminous balloon silhouette in the same ruffled material, and falls below the knee.

Coughlan paired this with the Averly 100 by Jimmy Choo in black, a whimsical style that features a pointed toe silhouette with one black tulle bow on the toe, and another on the opposite ankle strap.

She added some sparkle with a stunning sapphire necklace and ring set, featuring a delicate silver chain and large statement sapphires. Her makeup was kept fresh and dewy, with a peachy nude lipstick and a classic flick of black eyeliner.

Her hair was styled into a modern half-up-half-down style, with her blonde bob lightly curled at the end, and half tousled into a loose bun at the crown of her head.
