art defines fashion doesnt it? i mean if a person doesnt know art, they wouldnt be able to design something "beautiful." and to answer your question, art does not have to be beautiful in visual sense ... but it describes something, expresses something. A person dresses in fashion because they express themselves by it. Same with paintings. In terms of profession, fashion is a form of design. You design everything on a shirt or dress, and you design how you dress, just like designing a painting.
I'm not sure what to look up, but look up fashion design, fashion designers, artists, and just research on those definitions
