looks like she had some shiny skin and tried to face powder it too fast
I think it is just a special face powder that photographs better than regular face powder and can’t be seen under ordiary light.
Not a big deal. Shows you the Brits have their heads up their butts if they think this is the most important thing they have to worry about.
Beheadings, trafficking of British schoolgirls and gang rapes are fine but, God forbid someone’s makeup photographs badly.
Shame on them for pointing it out.
She used a photo finishing powder but apparently it wasn’t applied well and evenly with a brush.
Otherwise she cut an elegant figure. So much better carriage and bearing than the current WH.
