They don't have to have dwarfism (though that would be a plus), but any story involving shorter women would be greatly appreciated.
I can't speak for other writers, sorry, that's not a detail that stands out in my memory, but I can suggest Size Matters in the transformation section.
You can't go wrong with a story by Lobo. Also check out these stories with short or tiny woman.

I found this one: http://www.dollstories.net/storiesad/caroline_doll.html (http://www.dollstories.net/storiesad/caroline_doll.html).
It just proves there is something for everybody at Gromet's Plaza, but we don't always remember where it is so it pays to explore the archives.
