From the lost gallery's photostream on flickr. The Wikipedia article includes a small image of Alexandrine wearing a forest green dress.
Princess Alexandrine's dress is typical of the time around 1840 with a small full skirt and double lace bertha. Her coiffure does not have side curls, but has a similar outline.
