I purchased this photo at the Antique Shop in Park Rapids, Minnesota.
Thanks for stopping by, do come again:)
Update from Norkio:
She is most definitely not the maid. :-) That is a beautiful example of an Edwardian ladies gown. It's technically from 1900-1918, but this dress is in the mid-period and best associated with the Titanic era fashions. You could probably date this 1910-1913.
