What evidence shows that karana took pride in her appearance even though she was alone on the island?

Even though she lives alone on the island, Karana takes great pride in her appearance. In chapter 18, we are told that Karana takes time to make a yucca skirt for herself even as she spends time taming her pet birds, Tainor and Lurai.
Accordingly, Karana takes time to soften yucca fibers in water before she braids them into twine. She designs her skirt to have lengthwise folds. The beautiful skirt is open on both sides and hangs gracefully to her knees. Karana also makes a sealskin belt to go with the skirt. She completes her look with sealskin sandals, which she proudly wears on walks over the dunes.
Often, Karana makes a wreath of flowers to wear on these walks. More often than not, she also wears her beautiful new skirt and sandals during her lonely excursions. We can see that Karana takes great pride in her appearance from the way she fashions her clothes: they are both beautiful and durable.
In chapter 20, we have further evidence that Karana takes great pride in her appearance. We are told that she kills and skins cormorants from Tall Rock so that she could one day fashion a skirt for herself from cormorant feathers. Later, when Karana moves to the cave in the ravine, she makes sure to take along her prized skirt, beads, earrings, and the cormorant feathers. Despite her loneliness, she always makes sure that she looks presentable, a clear sign that she takes great pride in her appearance.
