ballet is about expressing feeling through movement, music and costumes.

Yes. Drastically. Sometimes....most of the time, it depends on the style of ballet, the ballet company and who makes the costumes. For example: The Swan Lake head pieces used to be all feathers. They went on you forehead (where the hair stops) and over your ears. Now they are (ABT style) crowns. A lot of old Russian Vagonava costumes are still in use and it is tradition to use the old costumes for a Nutcracker of Copellia production.
There are all sorts of different costumes; From Animal costumes, to ballet costumes. So the costumes vary, depending on who was on the stage at times.
Leggings and a fitted top/jacket, depending of the ballet.
a ballet costume or a ball gown costume
Yes And YES !!
Usually ballet dancers wear a body suit with a skirt or tutu, or a dress always with tights inculded and ballet slippers
For ballet class- Leotard, pink ballet tights, silk/leather/canvas pink or black ballet shoes, a ballet skirt (optional) On stage, you either wear a tutu, or a long ballet dress. But, it could be anything!!
In the early 1400's in Italy. Ballet used to just be men in heavy costumes doing ballroom dancing.
Ballet is danced in many different costumes depending on the plot of the story, but one thing that is indispensable is toe slippers.
You can find costumes pretty much any dance website. I suggest Curtain Call. They have a wide variety of styles. https://curtaincallcostumes.com/about-us.php
