Dona was a "low hanging fruit" in the royal marriage stakes. Even after the announcement, the Prussian court still have to investigate if her family was "untainted" enough to marry the heir to the throne (Remember Wilhelm I had to give up Princess Elise Radziwill for that even though her mother was in fact a Princess of the House of Hohenzollern). Not to mention the surprise of QV who though Willy would pick the prettier Calma (Caroline Mathilda, younger sister of Dona) than the pain Dona. Dona of course was not ugly, but hardly comparable to Ella in looks, there is no disrespect in that but a hard cold fact. Vicky was rooting for Dona & Calma for Willy, but when Dona married Willy, The younger woman's disrespect and rudeness to Vicky made many readers dislike the "dowdy woman with impossible hats". Willy himself even asked Louise of Coburg (Belgium) to select's Dona's hats & clothes, that is how much he respects her.
