Several costume options are possible: A common and easy to do costume for women is take a black dress and pin cloth leaves to it with a natural wreath crown (woven grape vines with some baby's breath works well). Peacock feathers can be added to the rear of the dress as an additional embellishment. For men can go with a trapper look of animal skins which you can usually pick up at flea markets through out the year (you'd be suprised how many single guys who are into hunting and trapping suddenly find a reason to get rid of all those "dead animals" once they get married.) Fantasy themes like Satyr's and Faeries tend to work well also. I would strongly suggest avoiding animal costumes like gorrillas and bears. Popular in the USA also is NAT (North American Tribal) themes based on traditional dress. Check with your local tribe for suggestions.

The way to dress your child for a fancy dress theme environment is to pick out a lovely dress. After putting the dress on them, accessorize the dress with stockings or socks with sandals or dress shoes. Purses or a necklace can also be a cute accompaniment.
A halloween costume is a costume/fancy dress outfit in a distinctive style to copy the dress of a particular person, character, animal or object. This is then obviously worn at Halloween, often to parties of trick-or-treating. The halloween theme means they are normal scary characters from horror movies or generically scary things such as zombies.
Go for it! Make it as fancy as possible!
