Clothing can be used as a motif in Biblical literature and sometimes is used to depict an element about the person wearing it. In the book of Genesis, we find several cases describing clothing, and in the case of Ya’aqov and Esav, it is a fundamental element in the storytelling.
וַתִּקַּח רִבְקָה אֶת בִּגְדֵי עֵשָׂו בְּנָהּ הַגָּדֹל הַחֲמֻדֹת אֲשֶׁר אִתָּהּ בַּבָּיִת
“Then Rebecca took the best clothes of Esau her older son, which she had in the house” Gen 27:15
The Hebrew calls Esau’s clothing חמדת which is translated as best/favorite.
