The pledge button is a small Norman shield of blue bearing a white Sigma Chi cross.
When suitably dressed, the pledge may wear his button or pin. With a suit or sport coat, it is worn in the buttonhole of the left lapel or as close thereto as is practical. When a coat is not worn, it is placed on the left side of the shirt front between the pocket and buttonholes and over the heart. Pledges should refrain from wearing the pin on a t-shirt, sweatshirt or other non-collared shirt. It may be worn on a pullover sweater.
The Fraternity seal is circular. Around the top of the outer edge is the name Sigma Chi Fraternity, and at the bottom are the numbers 1855. The central portion contains seven stars and a seven-branched candlestick.
The flag is rectangular, the length being one and one-half times the width, the upper half being blue, the lower half being old gold, with a white Sigma Chi cross in the center standing upright and parallel to the lesser sides.
The Crest is a Norman Shield of blue bearing a white Sigma Chi cross, the shield being surrounded by a scroll and a rest of an eagle’s head holding a key. The public motto, “In Hoc Signo Vinces” is placed below the shield on a scroll. The meaning of our public motto is, “In this sign you will conquer.” It is pronounced: “in hoke sig’no win’case.”
Our flower is the white rose.
Our colors are blue and old gold.
The badge, a Sigma Chi cross of gold and of white and black enamel, contains two chains connecting the upper arms, crossed keys on the upper arm, an eagle's head on its right arm, a scroll on its left arm, clasped hand and seven stars on the lower arm, and the Greek letters in the center. The symbols and borders are gold, with white background on each arm, and black background in the center.
Only initiated members of the Fraternity may wear the badge. When suitably dressed, members may wear the badge over the heart, on the left breast approximately midway between the waist and the neck. It is to be worn with the upper arm slanted slightly toward the left shoulder. It may be worn on a collared shirt, pullover sweater, or vest, but never on the lapel of a coat.
While only initiated members may wear the badge, coat of arms or Sigma Chi Greek letters, this regulation does not apply to such items as pins for sweethearts, wives or housemothers. Recognition pins are to be worn only in the upper corner of a coat lapel approximately one-half inch from each edge (and not in a buttonhole or near the lapel’s center).
