Example 1: He’s obviously trying to make some kind of statement by dressing like that. (macmillandictionary.com)

Example 2: The furnishings here make a statement about the company. (thefreedictionary.com)

Example 3: The car stopped at a red light. A woman in platform heels was standing on the corner, one hip jutted out. Like Molly, a hooker, but older — maybe eighteen, with lustrous black hair that tumbled all over her bronzy shoulders. Black hair would be nice, thought Molly wistfully. It made a statement. It was not an in-between color, like Molly's limp hair, which was neither blond nor brown and made no statement at all. (Tess Gerritsen, "Life Support")
