Hello and apologies for not getting posts done earlier; the weekend engagements became too much for me to keep up with! We have several outfits worn by the children to cover, beginning with the visit to Cardiff Castle in Wales by Prince George and Princess Charlotte. 
More from this Sky News story.
The royal youngsters joined their parents the Duke and Duchess of Cambridge to meet entertainers staging a show in honour of the Queen at Cardiff Castle.
The Cambridges were set to learn about the lighting, sound, and visual effects for the show, watch rehearsals and meet the hosts, Aled Jones and Shan Cothi.
The visit included a walkabout. This BBC story has details.
Emma Thomas, from Cardiff, met the Royal quartet and said: “Prince George walked right up, shook my hand and said ‘I’m George’.
“Princess Charlotte was eyeing up the sparkling shoes of the lady who gave the flowers to Kate.”

The family also visited the Royal Welsh College of Music and Drama. 
This was a lovely shot of the children. 
Now for our look at what the young royals wore, starting with Princess Charlotte. She was in the Amaia Kids Razorbil Coat ($179) first seen at Prince Philip’s service in March, and what looks like the Rachel Riley Forget Me Not Smocked Dress ($155) worn on Easter Sunday. 
Prince George was in a navy jacket that look like it is cotton, with notch lapels and patch pockets, and a pair of cotton trousers. His shoes are by Papouelli, the Parker Brogue (£98) in brown suede. 
Here is a quick video recapping the visit.
So lovely to meet the stars and team behind tonight’s concert. We had an extra special drum demonstration for George and Charlotte, saw a stunning performance from the Wales Youth Choir for Good and had a sneak peak at how the show will come together.
Have a great time! ??????? pic.twitter.com/CDHJAdnt0A

Saturday night we were delighted to see Prince George and Princess Charlotte again, this time at the Platinum Party at the Palace. 
More from this Metro story.
There were huge cheers at the Cambridges arrived for the star-studded show, featuring performances from the likes of Elton John, Diana Ross and Queen.
Charlotte, seven, wore a red dress and waved a Union Flag while George, eight, was fully suited and booted.
The Princess wore three red pieces, a dress, cardigan, and cape. The Red Riding Hood Velour Cape ($33) is made by Souza, a Dutch brand that does costumes and party outfits for children. It is made of lightweight polyester and has a velcro strap fastening at the neckline. 
Here is a closer look at the trim. Another fab ID from Found By Bojana!
The Princess’s dress was a tough one to identify, but ultimately it looks like it is a design from Monsoon, the retailer’s Sequin Cape Sleeve Dress (£20.50 most recent price). 
The vibrant red frock is 100% polyester in a chiffon weight with sequins on the bodice, cape-style sleeves, a satin bow at the waist, back zipper, and a full, floaty skirt. Many thanks to The Cambridges Royals for such a fab ID!
The next day, Sunday, we were all surprised when a video was released with photos of all three Cambridge children baking with their mother. 
The photos were shared on Instagram by the Duke and Duchess of Cambridge. 
Louis looks fierce as he sifts flour. 
The caption reads: “Baking cakes for the local community in Cardiff to enjoy at a Platinum Jubilee street party taking place today!” 
You can see the cupcakes they were making. 
If you are wondering about the finished product, here is a photo shared by Narelle Edwards. They look mighty yummy!
Now for what the children wore in the photos. Princess Charlotte wears two different tops. One is the Charlie Pom Jersey T-Shirt ($28) by royal favorite, Boden. Made of 100% cotton, the design is described as having “a loose boxy fit,” and features a back keyhole opening and button with decorative pom trim at the neckline and cuffs. 
Here is a better view of the details. 
Thank you to Becky on Facebook and Found by Bojana for this ID!
The tee comes in a mix of colors, and the pom trim is used in a broad mix of fun items like the Charlie Romper, the Charlie Tank Top, the Charlie Dress, and Charlie Shorts.
The pink top looks like a Next Polo from a cotton polo three-pack. Below right you see another from the package of three that the Princess has worn. 
A better view of the details. 
The Princess is seen wearing the polka dot polo in her 7th birthday photos. 
The shorts worn by the Princess look like they are by Mayoral, the Blue Cotton Jersey Shorts ($24) a brand worn before by the Cambridge children. Made of 95% cotton and 5% elastane, with front and back pockets, pom trim, and a faux drawstring with a tasseled trim. Thank you to Bojana for identifying these!
It looks like the Princes were twinning, both wearing the Sfera Basic Polo Shirt in 100% cotton.
Prince Louis also wore Sfera’s Basic Chino Short (€13.39, about $14 at today’s exchange rates) The shorts are 100% cotton with a zip front and pockets on the front and back. Thank you to Found By Bojana and Pauline Repli-Cambridge for these IDs! For those curious about the brand, Sfera is owned by El Cortes Inglés, Spain’s largest clothing retailer. NOTE: The post originally said Prince George was in the Sfera shorts. That was a mistake, it is Prince Louis wearing the shirts. Thank you to Caitlyn for her comment pointing out the error.
Our final ensembles are those worn by all three Cambridge children for Sunday’s Platinum Jubilee Pageant.
This was the final event of the four-day Platinum Jubilee weekend. 
Another view of the children. 
The pageant was more than three hours long, quite a while for anyone to sit, let alone children.

After the pageant ended, the Cambridges made their way inside Buckingham Palace to join the Queen, Prince Charles, and the Duchess of Cornwall on the balcony. 
Now for our look at what the young royals wore, starting with a grown-up-looking Prince George. 
He was in a navy blazer, cotton shirt, and a rep stripe tie, none of which have been identified. Now for our review of what Princess Charlotte wore to the pageant wore.
She was in the Amaia Kids Razorbil Summer Coat (£140, about $175) in ivory. Made in 100% cotton, the coat is similar to the winter styles we have seen the children wear, but much lighter weight, available in sizes 1 to 10 years.
Here you see Charlotte wearing the Razorbil for Christmas church services in 2019 and for her first day of nursery school in January 2018. 
Beneath the coat, the Amaia Kids Bristol Dress (£105, about $130 at today’s exchange rates), described as being made from European plumetis, a fine lightweight fabric with a raised pattern. The cotton dress features a soft floral print, pleats on the bodice, and a Peter Pan collar with ric-rac trim, as well as ric-rac at the sleeve hem and waistband.
Thank you to Found by Bojana and Royal Fashion Police for this ID.
Now for what Prince Louis wore. 
He was in a short set with cornflower blue shorts that have an elastic back waist and pockets, an ivory blouse trimmed in coordinating blue stitching, and navy anklets. When arriving the Prince wore an Amaia Kids Redwink Jacket (£85, roughly $105). The piece has a round collar, welt pockets, and button front.
This is a style we have seen the Prince wear before.
It is also a design Prince George wore in both in 2016 and in 2017. The jacket worn by Prince Louis this weekend does not have the contrasting trim seen on the previously worn style, and it is made in 100% cotton, as opposed to wool.
Here is one more group photo from the weekend.
And a final image that was shared on social media by the Duke and Duchess, including the message accompanying it. 
I think Prince Louis wore the same shirt that his father wore to Trooping the Colour in 1986. Their shorts look different though.
I think George wore that white shirt trimmed in blue several years ago. I remember thinking at the time, it seemed more suited to a girl than a boy.
Anyone else notice the KitchenAId mixer? I am a proud KA groupie.
He’s worn a similar shirt but the ones he’s worn never had a pocket and had a straighter piping. Louis’ is more zigzag and has the pocket.
I for one love to see girls in smocked dresses. My daughter wore them up to the age of ten. People always complimented her on how nice she looked. For young boys, I was always partial to the Eton jacket and shorts with a white shirt – my sons wore those up to the age eight at which time they would begin wearing long pants, jacket and tie (a bow tie until they learned how to expertly tie a regular tie). In a way, it was much like a formal uniform that they wore for church and public outings where dressing up was necessary.
The Cambridge children always look appropriate for whatever activity in which they engage. They also always seem comfortable in what they are wearing – no picking at the collar; shirts neatly tucked in; George’s tie always neatly knotted and in place. That indicates that the clothes that are chosen for them to wear are such that the clothes “are not wearing the children” rather the other way around demonstrating that they feel at ease and so are pre-disposed to behave in the manner appropriate for the occasion – even Louis, who was really on display for his first big royal events as a young four year old, behaved quite well for what were really and truly hours long events.
In the cupcake photos, I believe the prince in the Sfera shorts at the mixer in the background is Prince Louis. In another shot posted, both princes are seen in the background: Prince Louis, in the lighter shorts, on a step stool, and Prince George, in navy shorts, feet on the ground. It may have simply been a typo on your part, but I wanted to point it out to prevent any confusion.
Thank you, Caitlyn! ?
It was nice to see Charlotte wearing a few outfits that weren’t blue. With her darker hair she could wear just about anything. The off white color, though seemed to wash her out.
I would be pleased if Princess Charlotte never had to wear another smocked dress. To me, it’s a look that girls quickly outgrow by their fourth or fifth birthday. The Peter Pan collars can go, too! I do love her coats in their many iterations and she is such an effervescent child but always with the proper degree of decorum. It’s wonderful to see Prince George coming out of his shell and he seems comfortable wearing all sorts of clothes. Prince Louis is a character (as most four year old boys are!!) and it’s always fun to see him wearing something that either George or William has been seen wearing before.
I respectfully disagree about the smocking on Charlotte. I think it’s darling and I hope she wears smocked dresses for another few years. Childhood is so fleeting. I’d much rather see a child dress in styles traditionally associated with young children for longer. I hate seeing George in a suit now. Logically he’s about the age where it’s culturally expected. But still, I wish young boys had a few more years before they’re expected to dress the same as grown men.
I agree with you there. The smocked dresses are gorgeous.
