I say: Its chain of transmission is good, owing to the well-known disagreement regarding Muḥammad ibn ʿAmr—namely, Ibn ʿAlqamah al-Laythī al-Madanī.
Wāqid is trustworthy and is among Muslim’s narrators.
The second is ʿĀṣim ibn ʿUmar ibn Qatādah, from Anas, who said:
“I saw Ukaidir’s outer robe when it was brought to the Messenger of Allah (may Allah bless him and grant him peace). The Muslims began touching it with their hands and marvelling at it, whereupon the Messenger of Allah (may Allah bless him and grant him peace) said: ...” He then cited the hadith, omitting that clause.
It was transmitted by Aḥmad (3/238) through Ibn Isḥāq, who said: “ʿĀṣim narrated to me ...,” and so on.

The third is ʿAlī ibn Zayd ibn Judʿān, from him, who said:
“Ukaidir of Dūmah presented [it as a gift] ...”—the hadith, without mention of the gift. In one version, he added:
“Then he sent it to Jaʿfar ibn Abī Ṭālib, who wore it. The Prophet (may Allah bless him and grant him peace) said:
‘I did not give it to you for you to wear it.’
He said, ‘Then what should I do with it?’ He replied:
‘Send it to your brother, the Negus.’”
It was transmitted by Aḥmad (3/111, 229, and 251) and al-Ḥumaydī (1203), in abridged form.
Ibn Judʿān is weak, and the final clause in his report is rejected in my view. Allah, Exalted is He, knows best.
There is also a fourth corroborating narrator: al-Zuhrī, from Anas, who said:
