Outdress → It is formed from "out-" (meaning outside or beyond) and "dress" (from Old French *drecier*, meaning to arrange or put in order). The word "outdress" means to dress in a way that is more elaborate or stylish than someone else, essentially dressing beyond or outside the norm.
Think of dressing 'beyond' ('out-') what is usual or expected — that's why outdress means to dress more elaborately than others.
