Stars from singers to supermodels were among A-listers at Princess Eugenie’s royal wedding, but some of their fashion choices raised eyebrows.

Catwalk model Cara Delevingne wore a black tailored suit with tails, a tie, and a top hat, with her look compared to a character from Oliver Twist by a bridal expert.

“Of course it’s okay to wear a mannish power-suit to a wedding. It’s modern, stylish and cool. Love the Artful Dodger look.” said Peta Hunt, editor at large at You & Your Wedding Magazine.

Delevingne posted on social media a side-by-side picture of her as a child wearing a similar all-black outfit with the caption “Who wore it better???” after earlier joking she was “showing up the lads” in a post.

Fashion queen Kate Moss took her seat in the front row wearing a delicate monochrome polka dot outfit, while supermodel Naomi Campbell turned up clad in a textured black knee-length dress with white detailing.

Sarah Allard, editor at hitched.co.uk, thought Campbell pulled off the look – but was less convinced about X Factor judge Ayda Field, who chose all white.

“Wearing white or any shade of white to a wedding is commonly considered a huge no-no, even more so for a royal wedding,” she said.

Field entered St George’s Chapel at Windsor with former Take That singer husband Robbie Williams.

Their six-year-old daughter Theodora was one of Eugenie’s bridesmaids.

Undoubtedly casting a discerning eye over the outfits on display was fellow guest David Emanuel, designer of Princess Diana’s wedding dress.

Other singers at the ceremony of the ninth in line to the throne included James Blunt, Ellie Goulding, Ricky Martin and Holly Candy, formerly known as Holly Valance, who was with her property tycoon husband Nick Candy.

Providing a touch of levity at the nuptials were funnymen Stephen Fry, Jimmy Carr and Jack Whitehall.

Arsenal fan Whitehall sent Jack and Eugenie his best wishes and joked about sitting next to former Tottenham Hotspur “low rent footballer” Jamie Redknapp throughout the ceremony.

The comedian wrote on Instagram: “I had to start pretending he was a dignitary called Rupert Redknapp The Duke of Hampton.

“An incredible day, seeing two of the kindest and most lovely people in the world tie the knot.”

Members of the Royal Family arrived in a group, with Zara and Mike Tindall among them.

The Duchess of Cambridge, wearing a dress by Alexander McQueen and a Philip Treacy hat, arrived with Prince William.

The Duchess of Sussex, who arrived with her husband Prince Harry at the venue where they wed just five month’s before, wore a navy dress and coat by Givenchy and a hat by Noel Stewart.

Harry’s old flame Chelsy Davy was also at the lavish ceremony, dressed in navy. She arrived with Lady Melissa Percy, the Northumberland heiress, who chose a striking powder blue flared catsuit-style outfit.

From the world of Hollywood were Lord Of The Rings and Armageddon actress Liv Tyler and Ghost star Demi Moore, wearing a dark jacket and long skirt and a burgundy dress and matching fascinator respectively.

Conservative peer and Downton Abbey creator Julian Fellowes was also present, with his wife Emma Joy Kitchener.

Lady Fellowes is a descendant of Field Marshal Horatio Kitchener, the former war secretary and face of the “Your Country Needs You” recruitment poster.

The broadcaster Richard Bacon, who recently recovered from a coma following a life-threatening illness, and former footballer Jamie Redknapp were also among the guests, as was Evening Standard owner Evgeny Lebedev.
