Katara’s hanbok is based on winter clothes of Joseon. The vest-like top is called teol-beja(털배자, sleeveless clothes with fur). Under it, she is wearing a skirt and jeogori, which is the basic form for women’s hanbok.
This drawing made the rounds on Reddit and Tumblr when I first posted it on DeviantArt. I figured I would post it here as mine, for posterity. I love it very much.
