The first site below has pictures of Medieval clothing for a Bishop, the second site and descriptions.
The dress of bishops and archbishops was based on that of a priest, with certain additions. A bishop wore exactly the same as a priest but with a mitre, a bishop's crozier and a ring.
The dress of an archbishop was the same as for a bishop but with much more elaborate decoration, mainly in the form of embroidery. Specific colours might be reserved for an archbishop and the cope (a large, full-length woollen cloak fastened with a single strap across the chest) would be frequently worn as day-to-day dress over the linen alb, stola, dalmatic, maniple and silk or wool chasuble. He would also have an elaborate processional cross instead of the crozier.

When they appear in public, modern popes typically wear a white simar over their usual clerical street clothes. The simar is similar to the priestly cassock (Keanu Reeve's character in The Matrix wore a black cassock, a long-sleeved, solid-colored garment that fits the chest and waist closely like a jumpsuit, except below the waist instead of pants legs, the garment is an ankle-length coat or robe.) The Pope's cassock is white and includes a matching cape, a mozzetta, which is draped across the chest and back and ends at the elbow. Wrapped around the simar is the fascia, a sash that is fastened by tying and with the long ends embroidered with the pope's coat-of-arms. The pectoral, a large cross, is worn suspended from a chain around the neck. Finally, the pope wears a matching white zucchetto, a skullcap somewhat similar to the yarmulke worn by Jewish men.
