From photographer Marie Labbancz:
When the bride, Kira, and her sister were children, her sister developed blood cancer. Kira was a perfect match, and was able to save her life. They have a very special bond. Her sister made this bouquet for Kira's wedding day, collecting brooch by brooch. It was truly an act of love.
