Our community does not have a formal dress code. Tradition holds you wear your “Sunday Best” for Sunday Mass and work clothing for daily Mass.
Put it this way: In a Catholic Church you are in the Real Presence of Our Lord Jesus Christ the King. Would you visit a king or president in obnoxious dress? So if wearing informal dress we should at least remember who we will be in the Presence of.
Veils for women are recommended but not required.
