Want a straight up picture of the dress itself? Hey, I have one right here:
This was from a girl (now woman, I suppose!) who had Kirsten growing up. The hat apparently did not survive.
For those trying to reproduce this dress, note that there is teeny-tiny piping between the bodice and sleeve, and at the edge of the sleeve. (The sleeves are not lined in white, that's just the other part of the piping you see inside).
