We can see the future now: your daughter will join a caravan of musical wanderers on October 31st. The key to this costume is the layers: the more the merrier.
Layer on mismatched flowery skirts, a few old scarves, and strings of costume jewelry. (If you can't find these items in your own closets, head to a thrift store).
Add some lipstick, and face paint.
Tie another scarf around the dancer's head, hand her a tambourine and an old purse, and candy will be in her future.
