Having been an "obessed" Mother of fabulous birthday parties, in a
previous life, I understand your plight.
I love the idea of the clear elastic.
But, if you need to have a wired harness you might consider wrapping
the harness with ribbons and then tip the with flowers, bugs, etc.
Or the harnesses could have tulle or organza petals attached to them to
look very etherial (msp?).
And my last suggestion is "presentation is everything", if you believe
in it she will too.
