First of all, the teaching comes from New Testament scripture, not Old. Today, that type of dress is typical for Oneness Pentecostalism or Holiness, which is already mentioned in the 1960–present sub-section. Also, there are some groups that teach and dress that way that aren't Pentecostal. And, incidentally, all 3 of those denominations above (plus the Church of God (Cleveland, Tennessee) and others) came out of the Holiness movement, and originally did dress that way, but changed between the late-60s to the early-80s (depending the particular group).
