That is really too 19th C. It would be completely ridiculous in 2019 to have extremely veiled ladies with invisible faces at a royal funeral. And why have the ladies to cover theirs and the gentlemen not? MeToo peeping here.
I thought the Grand-Duchess wore a little hat but I see I swapped her for another one. Yes strange indeed, like Màxima, Maria Teresa comes from a country where ladies use to cover the head when attending Mass. Mathilde has the same habit.
What has MeToo to do with covering once face because you suffered a loss and want to be, virtually, to be with "yourself"? Why would a mourning veil to be sexist...?! I think you got things mixed up here a bit, aren´t you?
Why then continue wearing veils at a wedding although everybody knows hardly any bride these days is a virgin...
Duc, veils were worn by WOMEN, that´s because we have a tradition for women to wear such an item; MEN never wore ones in human history so there is no tradition for male to do so. That is not sexist, that´s just a fact...
This is about royal protocol and etiquette. Royal ladies wore veils up to the 1990s (yes, also at Queen Ingrids funeral - at least by her daughters), a state funeral without attending ladies being veiled would have been considered pretty unthinkable - and this was until the end of the 20th century, not the 19th...
Wearing no hats has nothing to do with what country you come from as catholic, late Queen Fabiola obviously hated hats and didn´t wear one, even when attending mass, when it was not absolutely necessary. The spanish Queens hardly ever wear a hat, in or outside a church while Queen Maxima seems to wear hats all day long - obviously she, like her current belgian counterpart, seem to feel it is absolutely vital for a Queen to wear a hat even in 2019.
This does not answer, why the GDess didn´t even wear a hat for a full state funeral of her late father-in-law, former head of state, when she otherwise has no problems to do so (state visits etc.)...?!
