FYI: Princess Lea was seated in the front row next to the other royal guests. Seating order: Grand Duke Henri, Grand Duchess Maria Teresa, Queen Fabiola, Prince Philippe, Princess Mathilde, Prince Lorenz, Princess Astrid and then Princess Lea.
As for Prince Philippe: he attended an important reception for businessmen prior to the funeral. And obviously there was no time left to change clothes. Seriously, the only thing one can accuse him of is that he didn’t change to a black tie. But he made a real effort to attend both functions and that’s what counts imo. I’m sure the Habsburgs appreciate it.
BTW is it for sure that Prince Philippe is a knight of the golden fleece? I always thought King Albert and Prince Lorenz are the only Belgian royals with this distinction.
