floral bouquets for royal women at events

[sgl]

I have tried to find this info on the forums, but was unable to. What is the protocol for royal women and the bouquets of flowers that they carry at events? I have noticed that most royals are carrying bouquets of flowers while they are at official events. Who provides these bouquets? How are the flowers selected? Are many bouquets offered to the royal, and she selects from among them, or is there one particular person charged with the duty of procuring the bouquets for the royal?

I dont know who organises the bouquets, but they are always coordinated with the royals outfit.
Princess Mary is normally given them by someone related to the patron/cause the event is for, often a child.

Thank you for the information, Marmi. I have noticed that her flowers tend to coordinate with her outfits. Do they have advance notice of what she is wearing, in order to plan the bouquet?

I cannot recall where, but I read somewhere that royal women often carry bouquets at events to signal that they will not be shaking hands with people gathered (keeping their hands otherwise occupied).

I'd never heard that Kaatje, thank you. I have exams and assignments at the moment or I'd do some googling to see if I could find where you read it! Nevermind, its not that important.
