We have only seen Belle in her blue dress. A couple times with the Beast in France and at the Princess Storybook Breakfast at Akershus last October. I can't stand that yellow dress. I would guess that if you're doing the Storybook Breakfast, there's a chance you'll see Belle in her yellow dress. There is always ONE princess that does a meet and greet during the breakfast at the front of the restaurant. If it HAPPENS to be Belle that day, you're almost guaranteed she'll be in the yellow dress. Otherwise, I'd look her up in France or during the Storytime with Belle.
