Maybe. The US Copyright Office does grant copyright registration for toys. You might want to look at the Visual Arts Circular. When you apply for a Copyright registration, there is a brief examination by an attorney to determine whether your application meets the requirements, including whether your toy includes copyrightable expression.

Fortunately, the filing fee is inexpensive ($35 if you file electronically). Also, the registration process can take a long time, so, if you file on your own, keep very good records of all of your correspondence.

Good luck with your doll clothes fashion collection.
