Recently back from Netherlands and attending many social things with people of every walk-of-life, I found that this quality of Queen Maxima is very endearing to them. Was told, she was not born royal and is one of us. Was told, we all make dressing errors to some that look to always critique, but that is Maxima's personality and should always shine. Her family comes first and as long as King is fine with the way his wife dresses, all that matters. They love the silly jewelry occasionally and clothes that might not look wonderful on her, but that is their Queen and they adore her for it. They don't want her to look stiffy and always perfect because humans are not that way. That is her strength when it comes to fashion. You see her first, not the clothing and clothing doesn't wear her. She is always in charge, no matter how bad the outfit may be. Her outing in the Stuart tiara is a perfect example. (that was a perfect outing, but the tiara would be overpowering on majority of women)
To tell you the truth, although some of Queen Maxima's outfits are a bit out there, when on a proper State event, etc., she always is great and that is appreciated by them also. But, which tickled me, they love her silliness too. Yes, she is now married to royal born but she will always still be Maxima to herself and apparently the normal citizens love her ability to keep both. Just an interesting observation and wanted to share.
