The most popular reason for rewigging a doll is to create a new or unique character. With a different wig, a doll can look quite different from her original AG look. AG only has certain hair, eye, and face combinations available; those who seek to try other combinations may swap wigs between dolls or use brand new wigs to get new looks. Bitty Baby does not have a wig and one modification is to add a wig to her. Many wigs have side parts; removing and recentering a wig can preserve original hair but change looks.
