In Parliament in 1954, she waved two pairs of bloomers that were both labelled OS in front of an astonished House. She demonstrated that, although clothing was supposed to be in standard sizes and correctly labelled, much variation existed. The two pieces were quite clearly of differing sizes. Although opposed by clothing manufacturers, she received much support from the House, including from National Party members and standardisation was legislated.[5][6] On another occasion, she threw a stone onto the floor of Parliament to illustrate what buyers of bagged coal may find.[6]
