Duchess Kate attends Trooping the Colour in Catherine Walker's 'Astrid' coatdress

The Queen officially celebrated her birthday today with the Trooping the Colour parade. Although Her Majesty was born on 21 April, it has long been the tradition to publicly celebrate the Monarch's birthday on a day in the summer.

Today, the Duchess of Cambridge attended her fifth consecutive Trooping the Colour event and made her first official appearance since the birth of Princess Charlotte. During the parade, Catherine rode in a carriage with Prince Harry and Camilla, the Duchess of Cornwall, while Prince William was on horseback alongside his father, in their roles as Colonel of the Irish Guards and Colonel of the Welsh Guards, respectively.

Prince George stole the show today with adorable photos emerging of the little prince watching the parade from a window in Buckingham Palace.

The young prince then made his royal debut on British soil, joining his dad and members of the royal family on the balcony of Buckingham Palace to watch the traditional Red Arrows fly-past. It was a historic moment to have the Sovereign and three future Kings at one event. Prince George seemed to enjoy every minute of it!

And to top it off, Prince George wore the same outfit today as his own father did in 1984!  

Now on to the details of Kate's outfit. She wore Catherine Walker's 'Astrid' coatdress, tailored in a crisp textured woven ice blue silk with ivory floral pattern. It has a pencil line silhouette with a button front and neat rounded collar.

This is the second consecutive year the Duchess has opted to wear an ice blue ensemble. Last year, it was the Alexander McQueen separates, and year after year she has favoured traditional pastel colours for this event.

Today, Kate donned a new hat from Lock & Co. She wore the 'Marisabel' style in ivory.  The piece that has been handcrafted by Sylvia Fletcher, Lock & Co.'s leading milliner. The hat was sculpted using sinamay and then finished with a curled feather in a matching tone.

I'm yet to see closeup photos of Kate's earrings, but I believe she is wearing her diamond and blue stone pear drops. The designer remains unidentified.
