ITV's annual star-studded Palooza took place at London's Royal Festival Hall last night and it was a veritable fashion feast.
The Christopher Kane vest-style midi dress featured silver embellishment around the neckline. Holly paired the dress with a pair of black Gina shoes.
"Beautiful," said her pal Emma Bunton.
New mum Stacey Solomon enjoyed her first red carpet event since the birth of baby Rex.
"Excited to be dressed up and on my way to meet Joe," she said of partner Joe Swash.
"Not sure he will recognise me," she joked.
Stacey wore a tiered Olivia Rubin metallic dress, platform metallic shoes and a pair of chandelier earrings.
Fresh from celebrating her 40th birthday, Love Island host Caroline Flack wore a silver sequinned Zara shorts suit.
Caroline, who revealed she's off to start promo work for Winter Love Island soon, teamed her silver suit with a simple black roll-neck jumper.
Excited to be dressed up and on my way to meet Joe. Not sure he will recognise me.
Davina McCall and Loose Women star Andrea McLean brought the sunshine to the winter red carpet wearing beautiful bright yellow dresses.
Andrea looked stunning in a floor-length Nadine Merabi dress with a thigh-high slit and a keyhole cutout.
Davina, meanwhile, wore a one-shouldered asymmetric 1980s-inspired dress, complete with a structured shoulder pad.
Rochelle Humes, who was accompanied by husband Marvin, wore a floor-length Redemption dress and cute black fluffy heels.
The singer-turned-presenter showed off her toned pins in the dress, which featured a thigh-high split.
However, the mum of two made sure she was warm on the red carpet, accessorising her look with a black jacket.
Meanwhile, Coronation Street star Tina O'Brien dazzled in a beaded flapper-style cocktail dress.
Last week, Tina was out on the town with her Corrie co-stars as they attended Kym Marsh's leaving party.
