I do agree that the appearances of Marilene and Annette was much better than Laurentien and Mabel's appearances at the wedding -- although in Mabel's defence she is pregnant and further along than Marilene, so it might've been difficult to find appropriate yet nice maternity clothes for the occasion.
Unfortunately, as I like Princess Margriet's daughter-in-laws very much, they (and hopefully soon Anita and Aimee) will never be as high profile as Maxima, Laurentien and Mabel. I wish they were however, as I enjoy them very much whenever I see them out and about whether it be Queensday or more solemn occasions such as this one.
