Brittany Higgins has faced questions in the federal court about the dress she was wearing when she was allegedly raped by her then colleague Bruce Lehrmann at parliament house. Ms Higgins wore the garment to a liberal party function months later and told the court she did so to reclaim it. No findings have been made against Mr Lehrmann after a criminal trial was aborted. Ms Higgins is now a key witness in a defamation case against network ten as it seeks to prove the truth of its reporting.
