Oh dear friends, sorry to differ.
Its a definitive no for me, the beautiful and imposing russian pearl tiara from Queen Maria Cristina needs to be worn with the hair up (as most tiaras do actually). This way it looks like a beauty pageant tiara being worn.
Its the same dress and jewels as in the Netherlands (except for the big pearl brooch) visit and the result is not the best this time for Queen Letizia.
Also it looks unbalanced, altough the dress is beautiful my sugestion to upgrade this look would be wearing a nice brooch at the top center (its screaming for a brooch or a small necklace) above the order, and at least one nice bracelet.
I'm quite disapointed this time.

On the other hand is it known of any jewelry gifts to Queen Letizia in this visit by the Sultan of Oman? The Omani rulers are often very generous in such gifts to royal ladies (Queen Sofia, QEII, Diana Pss of Wales...) Thanks in advance.
