The Nadelhoffer caption - for the one on the left - does say it was commissioned by Queen Alexandra in 1904.
But I have never been convinced we have seen her wearing that one. Perhaps it was commissioned to be a gift for someone else (long shot I know).
I think it's more likely the captions were switched.
