The cassock-alb or cassalb is a relatively modern garment and is a combination of the traditional cassock and alb.
It developed as a convenient undergarment worn by clergy and as an alternative to the alb for deacons and acolytes.
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.
