Not only is this yellow dress Beauty and the Beast Belle costume pretty to look at but fun to wear as well! For a day, you can feel like a princess too and wear this nice, long, and flowing dress that you normally wouldn’t be able to. For this costume, make sure that you do your hair in the same way Belle has hers done in the movie. Accessorize it with a yellow ribbon or crown if you’d like. Wear some comfortable yellow shoes or high heels and you’re pretty much all set with your Beauty and the Beast Belle costume.
