I made Burda 8121 several years ago. I started sewing it in January of 2006. It was a new pattern then. The alterations I made back then still fit.
I made some additional changes to the pattern.
That’s the 2 fronts, with darts sewn, attached at the shoulders to the 2 backs. I have a protruding rear (that’s Sandra Betzina speak), so using 2 backs gives me room for my butt.
