Funny, she doesn't look like she's been buried! She looks alive and kicking awesome in this hanging lace and mummy wrap dress with an attached petticoat, matching corset and a beautifully draped neckwrap. She'll be totally into the way the lace and tattered fabric hangs down and looks ghoulishly pretty.  How about adding a pair of bandit boots and some fishnets and complete her undead look?
