The cassock-alb or cassalb is a relatively modern clerical garment. It combines the shape of the traditional cassock with the color of the alb and the collar of the amice. [1] It developed as a convenient undergarment worn by clergy and as an alternative to the alb for deacons and acolytes.[ citation needed ]
A white or off-white cassock-alb has replaced the traditional cassock and alb in some Anglican churches since the 1970s. This garment is not the same as the chasuble-alb, which is approved for use in the Roman Catholic Church in certain circumstances.[ citation needed ]
