Those of us who are Mums and Dads here will be reassured and comfortable, I'm sure, with seeing the Princesses Beatrice and Eugenie looking like healthy and well-nourished young women.
Their clothes mightn't be the most flattering (in fact, I was astonished by Eugenie's hat!) but I rejoice in seeing them looking so happy and wholesome.
If they're both comfortable in their clothes and presentation, who are we to object? Like many sane and unpretentious people in the world, the princesses might well think that they'll dress as they chose, and rats to the critics.
If so, I admire and applaud that attitude. All power to them.
