Expression "with arms akimbo"

[Jupiter]

Hi teachers,

In this expression, the word akimbo is an adjective after noun and the whole expression is an adverbial.

My questions: Is the expression "with arms akimbo" a prepositional phrase?

Can prepositional phrase have adjective at the end?

Thanks in advance

Jupiter
