In early 20th-century Albania, particularly in the Catholic regions around Scutari (Shkodër), a distinctive custom set the local Roman Catholic priests apart. Under the influence of local Albanian culture — and in contrast to practices permitted elsewhere by Rome — all priests and monks, whether foreign or native, were required to wear a prominent moustache.

A clean-shaven face would result in them being mocked as effeminate and potentially driven out of their parishes. They typically paired the moustache with a soutane or frock, and in the countryside often went without a hat, unlike the red fez of the Turks or the white felt skull-cap worn by Albanian mountaineers. This unique tradition reflected the deep blending of Catholic clergy with Albanian folk customs at the time.
