Funnily, she is not wearing a drop of jewelry. Kitty's style is just her joie de vivre and winning smile. It was no accident the matte surrounding her photo is covered with floating cherubs. I think she was loud in a sweet way--if that's possible. I just think her laugh would be one known to all proclaiming her arrival before the front door was yet to be opened to her.
On closer inspection, it is entirely possible that Kitty is wearing a wedding ring but, if she is, it blends with skin tone. She may also be wearing a brooch on her right shoulder or a string of beads around her neck. One things for certain is that she is holding something in her angel-clasped hands. Is it a hankie, a love letter, a teeny tiny kitten?
