Historically, it all depends on time and persona station.
Military Gear didn't fall off the face of the earth after it became "unfashionable"
But knights cared about how they looked. during the period in which maille was the primary armour, I think you would find maille to be relatively uniform among a single piece. But as it gets older, then you might find some variation from repair and such.
During the 14th century, however, a popular style of maille was wedge riveted/solid ring inter meshing.
