One outward symbol of this was the adoption of distinctive clerical dress. This had started with the black coat and white necktie which had been worn for some decades. By the 1880s it had been transmuted into the clerical collar, which was worn almost constantly by the majority of clergy for the rest of the period.
In the local churches, clergy are known officially as 'pastors' or 'associate pastors.' Although their functions are similar to those in other denominations, the Reformed tradition stresses preaching as a central concern, and 'preaching tabs', which project from a clerical collar, are still at times worn with a robe while performing this task.
The Rev. Dr. Donald McLeod of the Church of Scotland (Presbyterian) invented the neck-band shirt style. Protestant clergy had been wearing white preaching bands for quite some time; McLeod combined them with the detachable collar that was in use at the time. The Roman Catholic Church did not adopt them as streetwear for clergy until later. They modified Rev. McLeod's design into the tab-collar style.
