Hey, you'd better seek for some professional translation for reference while learning ancient Chinese poems.

Here's one version I look up for you: https://eastasiastudent.net/china/classical/li-bai-mengyou-tianmu/

霓为衣兮风为马，云之君兮纷纷而来下。

A rainbow for clothes, wind for a horse,the Cloud Immortals come down one after another;

虎鼓瑟兮鸾回车，仙之人兮列如麻。

a tiger strikes the harp, a phoenix rides a chariot; the immortals line up like hemp.
