If crown princess Mary would wear something like this, most of her fans will write here about her excellent style... I've seen on queen Rania more outfits like this. And they suit to her. And I think everything what suits to you is with you beautiful. And she is beautiful, too with headband.
I don't know. Maybe Rania's headband is like hat...
on this pic you can see other woman than Rania and I don't think her outfit is much more odd than Rania's. But maybe I just like Rania more than it can be normal and I can't see her mistakes. Then sorry.
Rania is perfectionist. She wouldn't wear something what isn't perfect.
