How does a child dress like a bear?

I know there is a clothes trunk which adults can use to dress as a bear but I have a child that is going thru a phase and she likes to dress as a bear however there are no children interactions with the trunk besides the normal ones you would have with any other dresser (plan outfit,  change outfit, etc.)  Nothing to select a costume.   She gets really sad when she isn't dressed as a bear but there is no way for me to tell her to change into her bear costume unless she does it autonomously.
