This is a vintage pattern from Hollywood patterns, number 475. I believe this dates to the 1940s but I could not find a copyright date. The pattern is for a misses gored skirt and blouse in size 16, bust 34. The pattern is fragile; there are some tears and wear on some of the pieces and the envelop is quite torn and yellow. The description reads: Two piece dress, lumbar jacket blouse and skirt with box-pleated front and back. Blouse has a convertible collar and shoulder yoke. Inverted back pleat, two patch pockets and long or short sleeves. Blouse is finished on a wide belt that buttons at the center front. Skirt may be regulation length or shorter for sports wear. This pattern has 13 pieces but they are marked strangely: there is no C, D, M, or N pieces though there are S & T ones.
