Well, a fashion doll is a toy that looks like a small person, usually with pretty clothes on. It's called a "fashion" doll because the clothes are really important and people like to mix and match different outfits for their dolls to wear.
Fashion dolls are usually made of plastic and can be different sizes, but they're usually around 11 inches tall. The most famous fashion doll is probably Barbie.
People like to play with fashion dolls and use their imagination to create different stories and adventures for them. They can pretend that their dolls are going to a fancy party or a cute picnic with friends.
Some fashion dolls even come with accessories like shoes, bags, and jewelry so that people can make their dolls look even more stylish. Overall, fashion dolls are a fun way for kids (and adults too!) to express their creativity and have fun.
