Skinny people dancing?

what do you guys and girls think? I'm skinny but wish I had more body fat in places like my arms because I feel like I look awkward doing some movements or dancing =/ also, any advice on how to get more fat on my arms? people have said use dumbbells but I think that would look equally "off". I know it sounds like a silly question and others would be grateful to have skinny arms but trust me it's not always pretty!
