One does not simply travel light...
Private jets, fancy dinners and glamorous engagements - travelling a royal sounds like fun, right?
A large part of being a member of the royal family is travelling around the world, meeting world leaders, visiting countries in the Commonwealth and keeping the UK's relationships with other nations strong.
When The Queen travels, she always has a packed schedule of meetings and engagements - and a lot of work goes in to ensuring she is properly dressed.
A 10-day tour could require as many as 30 outfits, according to the Mirror , with back-ups needed for every engagement in case something goes wrong.
Unsurprisingly, Queen Elizabeth doesn't have to queue up at the easyJet check-in desk and pay for extra baggage - instead hours of work goes in to organising and transporting the royal luggage.
Years ago, whenever the Queen went away she took three very large, leather wardrobes with her.
These had to be carried to the plane and up the steps by members of the royal team, which wasn't an easy task as they were extremely heavy.
But Angela soon realised they needed to come up with a more practical way of doing it, understanding it had become "a bit of a nightmare".
Her first idea was to replace the wardrobes with hanging bags, packing two outfits to a bag.
The Queen was happy with the new plan and everything went well until the Queen and Prince Philip's went to Italy in 2000.
They were greeted by torrential rain at the airport and, despite the rain, a member of the crew decided to roll the rail carrying all the hanging bags straight across the tarmac.
They got completely soaked and things got even worse when they were caught by a huge gust of wind sending the bags everywhere.
Angela writes: "I watched the whole thing happen in slow motion from the plane - I felt so sorry for them scrambling around trying to pick up Her Majesty's soaked clothes."
When they returned to London, Angela decided to search for a new alternative to the Queen's luggage situation, popping into House of Fraser to see if they had anything suitable.
She bought a number of lightweight cases on wheels - which they still use today.
Angela writes: "I'm happy to say that this has been a successful and very welcome change."
The cases are packed very carefully to check the weight is similar on both wheels to ensure they don't topple over.
