Una Healy has always had a flawless fashion sense. So much so, that the former Saturdays star has designed her own range of clothes and wows us time and again with her looks on Instagram.

So it's no wonder that for her slot as a guest co-host on Today with Maura and Daithí the Irish songstress turned out another incredible look.

Stepping into the hosting slot while Sinead Kennedy is on maternity leave, Una is a natural at presenting, having had plenty of experience in front of the camera. But it's her outfits that truly show she knows how to dazzle on screen.

The singer chose a stunning monochrome black and white sleeveless mini dress from Karen Millen for the occasion. Featuring black trim along the neckline and down the front, pocket details, a high neck and round gold buttons accenting the front, the dress was the perfect balance between sophisticated and fun.

She accessorised her look with a pair of pointed black crocodile print stilettos from her own shoe brand, Una Healy Original Collection, as well as a pair of braided gold hoops to match the gold buttons on her dress. A smattering of smaller delicate earrings added to the funky glam of her look.

A fan of the graphic black cat eye, Una kept her makeup feline and sultry, with a thick black swipe of liner, smokey contoured lids and bold brows. She added a swirl of peachy blush to her cheeks as well as a soft peach lipstick.

Her auburn locks were styled in a sleek blow dry, with a subtle curl to the ends and plenty of volume.

Una will be hosting today's episode of the show, too, and we're already looking forward to what look she'll pull out next!
