Doll customization is the process of altering or personalizing dolls to reflect individual preferences or styles. This can involve changing the doll's hair, clothing, makeup, or even facial features. Many enthusiasts enjoy creating unique dolls that represent different characters, cultures, or personal stories. The customization process often includes using tools and materials like fabric, paint, and wigs. Some people focus on specific brands, such as Barbie or American Girl, while others may work with ball-jointed dolls for more intricate modifications. Customization allows for creativity and self-expression in the doll-collecting community.
