We should come to the sacred liturgy appropriately dressed. As Christians we should dress in a modest manner, wearing clothes that reflect our reverence for God and that manifest our respect for the dignity of the liturgy and for one another (On Preparing to Receive Christ Worthily in the Eucharist). [Our] bodily demeanor (gestures, clothing) ought to convey the respect, solemnity, and joy of this moment when Christ becomes our guest (CCC 1387).
