Forget-me-not blue is the pastel Duchess Sophie always comes back to - it might've overtaken pistachio as our favourite this season

The royals love wearing a range of colours for engagements and visits, but there are a few hues that each of them gravitate towards the most.

The Duchess of Edinburgh’s wardrobe is packed full of different shades of pink, but she’s also a fan of pastel blue. Her latest look was full-on forget-me-not toned and the centrepiece was her Emilia Wickstead coat dress.

This was also Duchess Sophie’s Christmas Day outfit for 2024 and she re-wore this stunning piece for The Sovereign’s Parade on 11th April. The senior royal was representing King Charles as the Reviewing Officer and coat dresses are a go-to for these kinds of occasions.

They give enough warmth and have a structured design that feels smart and sophisticated. The Duchess’ coat dress had a lapel collar, long sleeves and fell to an elegant midi length.

The buttons that fastened it were concealed, creating a seamless finish, and the tie waist belt gave the dress even more dimension. It was impeccably designed and we would expect nothing less from Emilia Wickstead.

However, it was the colour that we can’t stop thinking about. It caught our attention the first time she wore this in December too, but it was perfect for a fresh April day.

Forget-me-knot is a warm-toned pastel and if you’ve ever wondered what colour suits you, then pastel blue works especially well if you have summer colouring.

Even if you don’t, though, don’t let that put you off trying this tone. It looks great with lighter neutrals like tan and white and is soft enough to not be overwhelming, even if you wear a full blue outfit like the Duchess of Edinburgh did.

This spring, pistachio green is having a surge in popularity, but forget-me-not blue has many of the same qualities and just feels a little more joyful and bright. Duchess Sophie complemented her dress with matching blue court shoes by Prada and a Jane Taylor hat with frill detailing.

She loves expressing her personality with her hats and the design added some fun to her otherwise very timeless ensemble. Her look for the Sovereign’s Parade was formal, but if you wanted to style pastel blue more casually that’s simple to do.

Your best white trainers or flat white espadrilles would look amazing with a forget-me-not blue dress. If dresses aren’t your thing, then a blouse, shirt or cardigan in this colour can be paired effortlessly with blue or white denim jeans too.

Spring/summer is the perfect time to embrace wearing different hues and forget-me-not blue is incredibly versatile.

Whenever Duchess Sophie wears it, it also accentuates her blue eyes in a lovely way. Aside from this coat dress, she’s also worn another predominantly blue outfit this year.

In March she attended an event hosted by the European Parliament Intergroup on Children’s Rights in Brussels and her outfit of choice was a Victoria Beckham co-ord in the shade ‘bluebell’.

She also wore a coat to the Together at Christmas carol service in 2023 and a fabulous dress to Ascot in 2022 that were very similar colours.
