The Cambridge children were treated to a special movie screening at Kensington Palace this week.
Prince George, Princess Charlotte, and Prince Louis joined their parents and special guest Sir David Attenborough for a showing in Kensington gardens of David Attenborough: A Life On Our Planet. More from Hello’s coverage by Emily Nash.
The Duke and Duchess of Cambridge and their children welcomed the legendary naturalist to Kensington Palace, meeting him outside in the garden after school on September 24.
Photographs shared by the royal couple show seven-year-old George and Charlotte, five, looking almost starstruck by their encounter with the TV star, apparently to the amusement of their parents and their special guest.
Below, a graphic from the film.
It is described as, “A broadcaster recounts his life, and the evolutionary history of life on Earth, to grieve the loss of wild places and offer a vision for the future.” This Kensington Palace Instagram photo gives you a sense of the setup for the special screening. 
The movie opens in theaters on Monday. It premieres on Netflix Sunday, October 4th.
Sir David had a special gift for Prince George. More from this Telegraph story by Hannah Furness.
…Sir David Attenborough had just the thing in his pocket: the tooth of a 23 million-year-old giant shark he found on holiday.
Sir David has personally presented Prince George with the treasure, which he found in the 1960s during a family trip to Malta.
The young Prince, who like many small boys has a fascination with fossils, appeared thrilled with the gift, shown beaming in a photograph and studying it proudly.

Back to The Telegraph piece:
The visit was a long time coming for the three children, who have all watched his television programmes.
On a previous encounter with Sir David, the Duchess told him: “The children were very upset that we were coming to see you and they weren’t coming, they’re massive fans of yours.”
Although William has “always loved nature,” he previously revealed that fatherhood has influenced his conservation efforts.
In a clip from his upcoming documentary, Prince William: A Planet For Us All, the father of three said that becoming a dad gave him a “new sense of purpose.”
“Now I’ve got George, Charlotte and now Louis in my life, your outlook does change. You want to hand over to the next generation, the wildlife, in a much better condition,” he added in the clip, which also documented William’s talks with Attenborough.
Prince William: A Planet For Us All will air on ITV in October.
Now for our look at what the children wore for their afternoon movie viewing, beginning with Prince George.
He was in a shirt by heritage brand Trotters, the Thomas Brown Blue Checked Thomas Shirt ($52).
Thank you to Pauline for her DM with the speedy ID of the shirt, and also to Princess Estelle Attire for sharing the ID.
The Prince could be wearing the pair of H&M chinos he has worn previously, another Pauline ID. They look similar to this style. 
He also has on a Vaello belt he has worn before, the Vaello Deep Blue Elastic Belt.
Unfortunately, I no longer see this exact style available for purchase online, although similar styles are offered. It looks like he may have had on the H&M chinos we have seen him wear before, but it’s I’m not comfortable saying definitively that is the case.
The Prince was wearing a new pair of brogues, a classic style with four eyelets and perforation on the toe box. I have not been able to find an exact match. They are similar to the style shown below from Trotters, but the Prince’s pair doesn’t appear to have the additional perforations on the toe above the ‘v-shaped’ perforation. 
Princess Charlotte is in a floral print dress with an oversized white collar with scalloped edges. 
I’ve not yet looked for Charlotte’s dress but will start as soon as I get the post published. UPDATE 11pm: With thanks to Mika on the WKKW Facebook page, it looks like the Princess might have been in this dress by Zara.
The style is called Floral Dress with Peter Pan Collar. It is described as a “flowing floral print dress with embroidered motifs featuring a Peter Pan collar, long sleeves with button fastening and front button fastening,” the dress appears to be out of stock. Below, another view of the dress.
And one more view better showing the detail of the collar and the colors of the little flowers in the print. 
The Princess appears to be in another pair of Hampton Canvas Plimsolls, this time in (I think) cornflower blue ($37). 
Prince Louis is wearing a sweater we have seen before.
It is the jumper his older brother wore in Canada in 2016. 
It is the ‘Harry Jumper’ in Larkspur Blue by Wild and Gorgeous, but it doesn’t appear to be available. 
The sweater is 100% merino wool, with tipping at the collar and cuff, and a front button placket. Beneath the sweater, he is wearing a blue checked shirt that I don’t recognize as worn by Prince George. I will look for it in a bit.
The young Prince is wearing hard-soled shoes in a classic T-bar style. I don’t believe they are the Jo First Walkers by Start Rite we have seen on Prince George. They are similar to this pair by Doña Carmen, a brand the children have worn often. 
I will update as soon as I learn anything more about Princess Charlotte’s dress or the boys’ shoes.
It’s noticeable that as the children grow so their clothes sit much better. As long as one suffers from the indignity of being obliged to wear a nappy it can be difficult to look like much other than a small blob. I find with Charlotte’s Zara dress here, that, although it shares characteristics with her younger baby smocks, this one looks quite grown-up, even chic, the gathering at the high waist and low ruffle being far enough apart for all the extra fabric to hang nicely.
The exaggerated collar comes across as more fashion statement than babyish and her Hampton trainers always look current. The subdued monochrome helps distract from the fussiness of yet another Liberty-style floral print.
And though George is also wearing traditional classics of check shirt, plain trousers, and brogues, he looks much more the young gentleman in these pics, especially since he’s sticking with full length pants. Louis nobly brings up the rear with his own check shirt and the tipped collar sweater. At least he is allowed long socks with his shorts which gives a touch of gravitas, even when you’re only two. The overall family colour coordination through varying patterns, solids, and textures is masterly and skilfully executed for the photo.
I love how everyone matches. One incongruity that did strike me was that while George and Louis are relatively formally dressed (button down shirts, brogues for George, cardigans, chinos/shorts, knee socks) as are the adults, Charlotte is barelegged and wearing sneakers (plimsolls? Is that word still in common use?) I wonder why that was.
I am in love with Charlotte’s summer blonde hair! That was me as a child, as it is one of my children. It always makes me sad when autumn and winter come and his hair reverts to brown.
George’s shoes are amazing 😍😍😍
In my opinion, Louis is wearing the Pepa & co shirt that George wore in Canada.
Love the little elephant logo on the shirt – another subtle ‘Catherine’ touch?…….
