There was much speculation last week that the Cambridges would travel to Scotland to celebrate the Queen's milestone as she overtook Queen Victoria as Britain's longest reigning monarch. There were more than a few disappointed fans when it emerged the royal couple were not in Scotland that Sunday. Happily, the family of four boarded a private plane on Tuesday and jetted to the Highlands in time to be with the Queen on Wednesday as Britain, the Commonwealth, and many around the world celebrated the historic occasion. This morning, William and Kate were snapped waving to happy fans as they arrived at Sunday morning services at Crathie Kirk, the church at which Her Majesty worships when she is at Balmoral.

There has been a fair amount of chatter about the mode of transportation they took north, i.e. private jet. According to
The Express, the plane is owned by the Duke of Westminster who is Britain's 9th richest man, clocking in at approximately £8.6 billion net worth. I guess he can afford to shuttle the future kings about every now and again.
The story said,
There were three cars waiting on the Tarmac for them as they landed. William and Kate got in one car with Prince George and then Charlotte, who was carried in a car seat, went in another car with the nanny. They had quite a few bodyguards with them.
It is interesting that the other time William and Kate took a private jet to Scotland was in 2013 when George was around the same age as Charlotte and had had the same limited exposure to the press. On that occasion, he had actually not even been presented to Prince Philip, which was the byline of the visit. I suspect the Cambridges are anxious to keep a very tight hold on pictures of Charlotte just yet. She has only been photographed twice since her birth, and doubtless they want to keep her from the lens for as long as they can. Again, we saw the same pattern with George. I think it likely they will relax a bit when the princess gets little older.
The other relevant element is sickness. Anyone who flies often can tell you that passenger planes are a veritable breeding ground for the common cold. Stuck in an enclosed space with 200+ people is an ideal environment to be exposed, and I often come down with something after commercial flights. Since Charlotte is still so young, I am sure that Kate wants to avoid that, too.
The Duchess recycled her Hobbs "Celeste" coat, which seems to be a popular coat for her. She first debuted it on Valentine's Day in 2012. At that time, she styled it much the same as she did today, with a black turtlenecked dress from Oasis.
Today's black turtleneck is not the Oasis. The Oasis was ribbed, but this morning's is quite smooth, much like the one Kate wore while pregnant with George. From left to right you can see the ribbing on the Oasis (picture form Liverpool) the smooth of her pregnancy turtleneck dress in the middle, and finally this morning's, which although grainy, is not ribbed and seems to have a similar sheen to the mystery piece in the center.
[Update] One of my awesome readers, Alejandra--a veritable fashion whiz--has suggested that Kate is wearing the
Séraphine dress from her trip to NYC. I think this is a significant possibility!
Kate wore the Hobbs again toward the end of that year when she was snapped, looking a little wan, on Christmas morning in Bucklebury. The princess was pregnant with baby George and stayed close to her mother and family for the holiday.
Finally, she wore it again a little later in the same pregnancy when she visited Grimsby in March of 2013. That time paired with the "Great Plains Cezanne" dress, and it is my favorite wear.
It seems Kate is wearing her Kiki McDonough Citrine drops, but I cannot be sure. What jumped out the most was, of course, Kate's new bangs--or, if you prefer, her fringe. The last time Kate did this it was not a huge success. You might recall the night she debuted those bangs. She was at the Natural History Museum in that green Mulberry:
I think they were a bit heavy and she let them grow out quickly. I know this is a divisive issue, but I really like the bangs she has now. They are lighter and give her face a new frame. I don't think Kate will stay with them very long, but it is a cute change-up that speaks to her process of "reintegration" after Charlotte's birth.
Kate will be whisked back to England soon, because she has a busy week ahead. I look forward to seeing you then!
