Sunstone announces temple garment change to two-piece.
"Temple Garments," Sunstone 5, no. 1 (1980): 49
In a letter to Church leaders dated December 15, 1979, the First Presidency has announced the introduction in February of two-piece temple garments. The new style garments will be offered in addition to and will be priced about the same as the regular one-piece variety. No explanation for or description of the new garments was given. Interestingly, the garments worn by Joseph Smith in Nauvoo were two-piece, equivalent to a shirt and pants.
