JoJo - You were REAL FAMILY to Greer and have every right to keep the dress. The Both of you shared a bond that transends titles and blood. You do not need to be sorry or apologize to ANYONE .... You have honoured Greer, and her memory, and her amazing gift, by not only taking great care of what you have of her-but in your own art and by unselfishly sharing it with others since Greer died, thus keeping Greer, her memory,and her Art alive.
(P.S. Don't Fuck with My JoJO )
