I think Mathilde is the Queen of facemasks- I love that she co-ordinates her outfit to include her mask too.
Full marks for Princess Anne though with her monogrammed mask!
Looking through these photos it's quite startling to see how many royals are using disposable surgical masks. There have been some examples of royals using more eco-friendly, not single-use face masks, but it's quite few in numbers. I would have thought (and hoped) that given so many royals are involved in causes related to the environment and sustainability that more would use multi-use masks to project a more eco-friendly image and to support the causes they are involved in. I understand the worry of the virus staying on the mask, but washing them according to the right instructions may reduce this risk. I also hope that when masks are disposed of they cut the bit of string, I've seen some awful photos of birds and animals getting stuck in the strings and being unable to fly/move etc.
