[TSteven]

When a man chooses to accept his bid from Sigma Chi Fraternity, from that point on he is considered a Sigma Chi pledge and may wear shirts, etc., with the words "SIGMA CHI" or "SIGS" but not the Greek letters Sigma Chi (a national regulation). He may wear Greek letters after initiation.

ETA: Only members may wear the badge or display the crest.

Pledges may also wear shirts, etc. with an unadorned white cross on a blue shield as found on the Fraternity's crest and similar to the Fraternity's pledge pin.
