This is why the duchesses don’t wear diamonds during the day

Despite marrying into a family with a veritable treasure trove worth of precious gems, you may have noticed that duchesses Kate and Meghan keep their jewellery low-key for daytime appearances.

While it always been unlikely that the pair would attend a lunch or afternoon event positively dripping in diamonds, some royal watchers have wondered why the duo eschew even a touch of sparkle when they’re out and about on official engagements.

But now etiquette expert Myka Meier has revealed that it’s all a matter of staying ‘appropriate’, and not appearing too flashy.

‘They have a team who know what is appropriate for the event they’re attending, and Meghan especially would be given a lot of advice on [what to choose],’ Meier explained to news.com.au.

‘Other jewels are worn pre-6pm. Before 6pm, you’ll see metallics, gemstones, pearls, sapphires. At night, you’ll see the diamonds come out, and that’s in order to not come across as flashy in your appearance.’

The exception to this seems to be formal occasions such as Trooping the Colour, when the family are all dressed in their finery. But apparently the royal rules don’t stop there – Meier added that everything from hemlines to heels are also very carefully chosen.

‘During the day, when the duchesses are on duty, we typically only see closed-toe shoes. We often don’t see too much of a platform for a day event, and we tend to see open toe only at red carpet events,’ she detailed.

‘For their formal daywear, we’re not going to see Angelina Jolie-style slits. There might be one in the back or a slight, slight one in the front to help them walk, but slits are for function, not for style during the day.’

To select the looks, Meier said that ‘royal aides can call in dozens and dozens of pieces, for just one sitting. At the end of the day, the Duchess of Cambridge or Duchess of Sussex would have the choice of the final piece, and everything else would be sent back.’

If only that was how we got dressed in the morning!
