dressed in a smart black suit 主语补语 还是状语

Everymorning, he left home dressed in a smart black suit.

书上把dressedin a smart black suit 划分为主语补语，我感觉是状语，随着状语？

老师能帮剖析下吗？

Every morning, he left home dressed in a smart black suit.

=Every morning, he was dressed in a smart black suit when he left home

备注：dressed in a smart black suit 为过去分词短语作状语，表示谓语动词动作left发生时，主语所处的一种状况。
