Photo Number Twenty-Seven

This is another photo from South Dakota.  This one was also taken at the Brown Studio in Sterling, ILL.  There is a name on the back of this one, Louise Neitzke.  So ..1888 to 1897 is the time frame we know about concerning Brown Studio..so how about guessing a date of 1890 on this one?   Personally I love the hat..but I also wonder what would cause someone to be photographed in a coat?  Was she going on a trip?
Thanks for stopping..do come again:)
*** Noriko came up with this info..Louise was a maid who worked for Thomas and Mary Galt.  We will date this photograph 1897.
