Fifteen inches is the ballerina doll size that actually leaves the house. It is small enough for a four year old to tuck under one arm and carry to a lesson, to a grandparent's kitchen, or into the back seat of the car, which is a completely different job from the tall display dolls that live on a shelf and get admired from a distance.
Katrina is made by Mon Ami, and at this scale she moves between dress-up prop and bedtime companion without any fuss. Among ballet dolls, this is the size that survives being taken places. Parents shopping for a first recital, a dance-class birthday, or an Easter basket usually land here rather than on the 22 inch versions, because a carry-size doll gets used and a display doll gets dusted. She is the ballerina stuffed animal that ends up in the photos. For a household choosing a first doll, carry size is the specification that matters most.
How do you clean a stuffed animal?
Soft dolls are usually spot clean only, meaning surface cleaning with mild soap and cool water followed by full air drying. Drying a soft-bodied doll completely matters because moisture trapped in the fill can cause mildew.
