More pics. Second dress. They look kinda sad/unconfortable. Maybe because his family(except his sister) didn't attend?
As for the tiara, he's no longer part of the succession line and I assume he can't afford to buy one.
I agree, the looks on the bridal couple's faces (his especially) aren't full of passion or happiness even imo.
At first I thought the tiara was part of the veil, but she wore it without the veil for the second dress so I guess it is a tiara. Just a very tiny tiara from the looks of it, something he might have been able to afford.
