Meet Os Domina :3
 
She is a young adult skeleton pony, who is into fashion and makeup :3
 
Despite her lack of skin, she has always had a love for trying to make herself look pretty, and so she likes to try out a lot of different paints and thing son her. She likes to color her bones in different colors and patterns, and is very fond of in comfy sweaters, since they make her feel more comfortable with her body c:
 
She was mostly isolated to herself growing up, as a lot of other ponies were scared of her due to her being a skeleton, which made her feel self-conscious and took up fashion to try and better her image and make her feel better.  
Despite this, she is a kind and friendly pony who likes to ty rand help others out.
 
She is able to detach her bones from herself and operate each part of herself independently, with her bones always coming back together to join up.
