A label expert qualifies the Duke of Sussex for his holding during the Lion King's European premiere

Prince Harry criticized an etiquette expert after hinting that the king was wearing a "bow tie ready" to attend the premiere of The Lion King.

London-based etiquette expert, William Hanson, tweeted a photo of 34-year-old Prince Harry, attending the glittering London event alongside 37-year-old Meghan Markle.

He wrote: "Are we in agreement that Prince Harry's bow tie tonight at #lionkingfirst looks a little" ready for use "?

He went on to suggest that despite the elegant appearance of a black tuxedo, the royal might not be wearing a dress shirt for the occasion.

Prince Harry was criticized online by William Hanson, an expert in etiquette, who hinted that the king's bowtie was "already done".

The etiquette expert shared a tie close to Prince Harry's tie, suggesting on Twitter that she looked "ready made"

The tag expert then pointed out that it seemed that Prince Harry had not worn a shirt for the prestigious premiere

William shared a close-up of Prince Harry's tie, claiming it looked like a "ready made" tie and criticizing the royal's lack of shirt on that occasion.

His wife Meghan joined Prince Harry as they paraded on the starry yellow carpet at the premiere of the event in London.

Harry and Meghan, who watched tonight's remake of the classic film of the '90s, then met the cast of the film.

And although this is Meghan's first film as a king, it's Prince Harry who seems to have escaped any eventuality with his outfit.

William also pointed out that Prince Harry had not worn an evening shirt for the prestigious London premiere.

It seems that it was Prince Harry's necklace that could have given the game. A dress shirt would have more traditionally a button-down collar and pleats on the front.

Prince Harry's shirt seemed more informal than that, with a simple classic collar and a button on the front.

This is not the first time the royal couple has faced a tragedy in recent weeks after having flouted the dress code.

Prince Harry was criticized by some for his appearance in his son's official baptismal photographs, in which he wore a pair of shoes and a long tie.

Last week, Meghan was swept away by the controversy while she was wearing jeans in the members only area when she was attending Wimbledon.

Although she did not break any rules by wearing jeans in the tribunes of the Court One – where there is no official dress code – an anonymous member accused her of Breaking the dress code by walking in a member's area where jeans are strictly forbidden.

Wimbledon sets a strict dress code for guests entering the members only area, which includes a clubhouse and dining rooms, as well as the Royal Box, which includes men's jacket and tie and no jeans.

But the dress code for the best places on Court One, known as Debentures, is "chic and casual" and there is no dress code for general viewers.

Earlier this month, some blamed Meghan for breaking the rules of dress while she was wearing jeans at Wimbledon.
