Sheikha Moza Bint Nasser Al Misnad, wife of the Emir Of Qatar, is visiting the Netherlands. Today she and Princess Máxima visited the Shell Technology Centre in Amsterdam. Princess Máxima wore a charcoal grey wide brimmed hat that worked, I think, because her hair was pulled into a low side chignon. I’m not sure grey is her best colour but it worked well with the colour blocking of her entire ensemble.
Sheikha Mozah looked elegant, as always, in navy blue. I love how stylishly she integrates her religious head covering with her couture – so very modern.

Love this style of hat on Maxima. While the color is beautiful, Maxima shines I
When she wears her bright or saturated colors. I agree that this hat shape looks best when Maxima wears her hair in a low chignon.
The Sheikha wears her headdress well, but since she wears them so often, she or her dresser must know exactly how to wear the turban, it’s colors, makeup, and earrings to her best advantage. There something to be said about wearing the same style when it suits a woman.
