New National MP Tim van de Molen said he was unaware of a message written on the suit sleeve: "Stay weird and shine on".
A backbench MP upstaged his colleagues and leader today when he arrived for caucus meeting in a new suit.
National and first-term Waikato MP Tim van de Molen said he bought the Christmas-themed suit and tie combo online.
Several journalists waiting for National leader Bill English peeled off to join
others keen to ask van de Molen about his attire, to bemused looks from other National MPs.
Asked if he was planning to wear the suit in the debating chamber today, he said he had talked to Speaker Trevor Mallard about doing so.
"And he suggested perhaps tomorrow might be better."
