I would like see if we can find examples of outfits which are influenced by the princesses countries.
For example:
This dress of Mary's which she wore in London (I found it in
this post by micas, if you are interested)
To me, this is definutely a Scandanavian dress, not something that one would see on sale in the Pacific.
And
this recent outfit of Letizia's I feel is the same, and I was wondering how many more examples we are able to come up with.
