Bunim, the son of Bunim, had a father who built a thousand ships and a thousand towns, and Rabbi honored him, for Rabbi honors the wealthy. And Rabbi said to him, "You should wear more expensive garments than what you are currently wearing, according to your wealth." [See Eruvin (Chapter 5, Mishnah 6) and there in the commentary of Rashi, Bunim, a student of Rabbi. See in Shas HaKadosh in the variant readings.]
