Musannaf Ibn Abi Shayba 13:476

Abu Bakr narrated to us, he said: Waki’ narrated to us, from Sufyan, from Mughirah, from Ibrahim and al-Sha’bi. He said: I said to them both, "What is your opinion regarding a *taylasan* (shawl) over a *taylasan*, and a *mustaqah* (fur-lined garment) over a *mustaqah*?" Al-Sha’bi said: "There is no harm in it." And Ibrahim disliked it.
