[...] The Order of the Elefant , the only Queen who wore it , had to be worn on the Queen's right side and not on her right leg.
The cordon can be worn off the hip / on the leg, out of respect (to show the complete Order with attached decoration). When tucked to the side the elephant, cross, star, whatever is not visible and a lady can also sit on it. It is optional to wear it this way and various royal ladies prefer to wear it "off side" indeed.
Examples:
Crown
Princess Mette-Marit with her Orange-Nassau "off side"
Queen Margrethe with her Elephant "off side"
Princess Marie with her Elephant "off side"
Princess Madeleine with her Seraphim "off side"
Princess Mette-Marit with her St Olav "off side"
Doña Letizia with her Carlos III "off side"
Queen Máxima with her Elephant "off side"
Queen Máxima with her Polar Star "off side"
I just saw
Blauw Bloed (Blue Blood), the weekly royalty program of the Dutch TV on my big crystalclear HD screen. The dress is actually surprisingly glittery, the pictures -especially the blurry videostills and twitterpictures- do no justice to the dress. The pictures we see were also made in the magnificent hallway but all lined up with dozens of photographers bombarding the ladies with flashlights. The images from the banquet itself, in dimmed light, revealed a whole different image. Very sparkly, all ladies looked wonderful.
