Police in Beatrice, Nebraska, covered the window at Hannah's Treasures after getting complaints about the mannequin.
The female fashion dummy had a pair of pants around its ankles.
The shop owner later put a bikini on the mannequin.
The lawyer for store owner Kevin Kramer says he may sue.
The attorney tells the Beatrice Daily Sun that nothing about the "naked mannequin constitutes obscenity."
The city attorney says he's reviewing police reports on the incident.
