And, while this is off topic, Emma also used Magic in "Manhattan", after she learned that she was capable of it, when they were going through security at the airport. Emma grabs Rumples arm after he has to reliquish the cloak that allows him to keep his memories. The only explanation, in my opinion, is that Emma tapped into her magic to help Rumple until he got the scarf back.

Now, back on topic. I agree with everyone that says ambiguous. There is not enough information to make any concrete decision. I'll even debunk the clothes aspect. Dorothy was a farm girl from rural Kansas in the original story. It would not have been out of the question for the rural people of the 60's and even the 70's, to have more old-fashioned clothing. They would not be up to date on current trends (many rural areas still aren't). So, I don't think you can really say with any certainty that her clothing was 30's clothing, as it would still be valid in the 60's, at least for the part of the country represented by Kansas. So the point is there is NOTHING that would indicate a preference for being in the LWM or being it's own realm (or part of some other realm). Hence, ambiguous.
