From what type of dress Meghan will wear, to who will be present and also who won't be.
MEGHAN Markle embraced a charity worker who was "deeply inspired" by her 2015 UN Women's speech during a visit to Edinburgh today.

The Royal visit is Harry and Meghan's first in Scotland but one of several in the run up to their big day at Windsor Castle on Saturday, May 19.
The trip to Scotland marks the fourth public appearance Meghan, 36, and Harry, 33, have made together. Prince Harry himself decided as normal to stick to his uniform tones of dark grey coat, white shirt and navy sweater.
Una Mallon, a mother of four, 47, from Belfast, said she thought Meghan would become "our new Diana".
"Meghan said, 'I'm not sure - it's sorted but it will be fun.' Harry said he didn't know". For example, she said she has no idea what she is doing for a hen party but it has all been organised by friends.
When a country shows you love, you show it right back.
However, the pony's previous antics suggest he well and truly has it in for the Royal Family. The beloved mascot was wearing a coat very similar to the one Meghan was wearing and even got a bit playful with Harry at one stage.
Crowds who had waited hours in the cold outside Edinburgh Castle, which dominates the skyline from a rock in the city centre, were thrilled with the smiling couple.
