The best things come in tiny packages. We love our adult Nap Dresses so much, we just had to make a tiny version. Meet the Tiny Athena Nap Dress. The Athena is a babydoll Nap Dress with our proprietary, elasticated nap smocking. About the Fabric Our Brushed Cotton is a medium-weight fabric with a soft, cozy, flannel-like feel that provides a little extra warmth for the colder months.
