In a letter to Louise Brownell (October 1891), Susy Clemens writes:
“Oscar Wilde was over here the other day, in a suit of soft brown with a
pale pink flowered vest, a blue necktie and some strange picturesque
white flowers in his button hole.” It is likely that the letter was
written from Berlin, because in two of the three previous October
letters, Susy references Berlin, including an address where they are
staying, and they are still there on the last day of October.

This is, of course, four years before the Oscar Wilde trials.
