Ahead of Royal Ascot 2026, royal fashion expert Monica Marriott-Mills (@themonicaway) gives Horse.Bet her day-one read on what the King and Queen will wear — and where she thinks they might surprise us.
King Charles is tipped for a purple tie on Tuesday’s curtain-raiser — even as the numbers point to blue.

I think everything the Royals do is very considered, and nothing is a coincidence when it comes to their fashion. Between the two, they wear more pared-back colours, and I think there are reasons behind that. It could be a mark of respect to the late Queen, who was known for her vibrant monochromatic looks, and there may be an underlying air of not wanting to overshadow her memory.

What I expect from Queen Camilla
Camilla tends to lean towards pastels, though she’ll occasionally go for a bright blue or an emerald. On day one though, I don’t think she will go for cream or white this time, I reckon she could surprise us and go for a yellow. She also tends to choose form over colour, opting for intricate details like feathers or embroidery, being more playful in the intricacies rather than the shade. White pairs well with a lot of colours, and it suits her colouring. I also think it’s partly to be harmonious with the event and let the jockeys and horses take centre stage.
What I expect from King Charles
The King tends to go for earthy tones, and blue ticks a lot of boxes for him. It’s a very patriotic colour, it is called royal blue for a reason, and it also complements a lot of what Camilla wears, so it doesn’t surprise me at all. It’s also simply a great colour for him, he knows it complements his colouring, and with a big team working on what he wears, they’ll strike that balance between what looks great and what’s appropriate for the occasion.
I think we’ll definitely see a lot of blues again this year. However, I don’t think he’s going to go wild, maybe a very soft sage or a purple. With purple being one of the most royal colours throughout history, I don’t think it would be a huge surprise for him to make an entrance wearing it on day one.
