Royal Ascot is known for attracting some interesting outfits, and its celebrity guests are no exception to that.
From Lisa Snowdon's burlesque style top-hat to cyclist Victoria Pendleton's understated affair, there was plenty to talk about as the famous horse racing event entered its second day.
Male guests fared better, with Ant and Dec kitted themselves out in dapper morning suits alongside their stylish wives Lisa Armstrong and Ali Astall.
Gok Wan looked equally dashing, while Niall Horan went in a simple grey chequered suit.
Here are some of the best and worst dressed celebrities at Ascot:
Best - Liz Hurley
Liz went for a form-flattering, elegant white outfit as she arrived for the second day of racing, in a stylish matching hat.
Worst - Lizzie Cundy
The name of the game at Ascot is classy and Lizzie just didn't match the brief. From too much sheer fabric to a satellite dish hat, all bets are off for this reaching the "best dressed" lists.
Best - Aliona Vilani and Vincent Kavanagh
Strictly pro Aliona Vilani and her husband Vincent Kavanagh upped the couple goals in the sartorial stakes with refined matching blue outfits.
Worst - Olivia Grant
Actress Olivia Grant made her first mistake with the oak leaf hat; the second was the feathers on her blinged-up coat.
Best - Victoria Pendleton
Olympian Victoria Pendleton played it safe but sweet in a spotted navy dress and complementing fascinator.
Worst - Jackie St Clair
Women are permitted to wear suits in the dress code, but the boxy number on Simon Cowell's former flame Jackie St Clair wasn't doing her any favours.
Best - Niall Horan
One Direction star Niall Horan accentuated his grey suit with a burgundy pocket square and tie for a polished, handsome look.
Worst - Tessa James
Ex-Home and Away star Tessa James looked set for a weekend at a festival rather than Royal Ascot.
Best - Amy Willerton and Daniel Day
The I'm A Celebrity star and her boyfriend looked both chic and smitten with each other as they attended the second day of the races.
Worst - Lisa Snowdon
Normally stylish Lisa appeared a little uncomfortable in her dowdy high-necked choice. And let's never mention the hat again.
Best - Gok Wan
A classic morning suit is rarely a wrong choice to cultivate an aristocratic air as Gok Wan found out to his advantage on day one.
Bonus best - The Duchess of Cambridge
While not technically a celebrity, all eyes were on Kate as she and William arrived by horse-drawn carriage to the race meeting. She wore a midi-length cream lace dress and wicker-style hat for the sunny afternoon out.
