Mum-of-three Holly shared an image of her outfit to Instagram ahead of the show.
She looked gorgeous in the black and silver Jenny Packham gown.
Her hair was curled and tucked back on one side using a Tilly Thomas Lux slide, and she opted for heavy eyemakeup.
Holly completed the look with shoes by luxury brand Gina.
Last week, Holly opted for a princess style pink gown and tousled hair.
And if fans thought she wouldn’t look out of place at a wedding – that’s because the dress was from The Wedding Club.
The brand is a stockist of designer bridal wear found in London and Birmingham.
Her dress featured a plunging neckline and nipped waistband which highlighted her figure.
The frothy pink choice was a departure from the week before, when Holly chose a vampy red column dress.
The gown was by British designer Sassi Holford who specialises in Designer Wedding, Occasion & Evening gowns.
A thin red belt effect emphasised her trim waistline as she grinned off to the side of the camera.
Her wedding rings could be seen sparkling on her left hand but her neck was kept free of jewellery.
She also wore earrings glistening in her lobes by Berganza, which claims to have one of the largest ring collections in the world.
The presenter’s hair was stepped up in an elegant chignon, with one piece of curled blonde hair kept loose.
Her shoes were kept hidden by the long dress in the photo but Holly shared with her fans they were by accessory designer Sophia Webster.
While Holly’s stunning dress commands attention, all eyes are on Gemma Collins tonight.
Last week, Gemma appeared subdued and nervous after falling on the ice the previous week, and fans are keen to see the TOWIE star get back to her best.
But what does her body language say about how she is feeling? Expert Judi James has watched her appearance and shared her comments with Express.co.uk.
