I particularly like Letizia's hair this way, and that tiara looks lovely on her--it is, in my opinion. oneo fhe prettiest ones of all the Royal Families. As for her outfit, it does accentuate how slender she is, but as long as she's healthy that is all that is really important. The Prince, as usual, is quite handsome.
I haven't really seen much discussion about Queen Sofia here--it's always centers on Letizia's weight, clothes, etc... I rather like Sofia's gown--although she looks better in lighter colors--the style is very flattering to her. I wish she had worn more than just a string of pearls, but she wears them beautifully. She is quite an elegant lady and I've always found her smile to be genuine.
