I can remember sewing clothes in high school and using the same size pattern as my off-the-rack clothing size. Some time in the mid-80s, a size 12 pattern became too small while size 12 off the rack was fine. The sizing charts used by the pattern companies remained the same, it was the mass-produced clothing that changed.
