This matches the jersey from Bestway Leaflet 1720, which I have seen for sale as a pdf on Etsy, if you want the matching set. It’s made in 3 ply and is for either 34 inch bust or knitted on bigger needles for a 43 inch bust. I have never seen these two sizes together on a vintage pattern before! It’s another one I found on my holidays, this one is from the Peak District.
