A vintage knitting pattern for a man's waistcoat, but which could also be suitable for a lady, in three sizes.
To fit: 32/34", 36/38", 38/42" chest.
You will need a double knitting yarn working to a tension of 5 sts to 1", using no. 5 (5.5mm) needles.
For success work a tension piece.
The original pattern is from circa 1950s, with the corners a bit bent, but overall good vintage condition.
