The back yoke is laser cut neoprene from Darn Cheap Fabrics. The mustard knit is very soft and semi-sheer, and was in stash. From somewhere. Can’t remember.
The two fabrics were vastly different in weight, but still attached without much trouble. Construction was shared between the sewing machine and the overlocker. The final top looks bigger than the last one, and the neckline is definitely lower despite cutting the same size. One of those examples of the fabric type making a difference to the fit!
The new True Bias Sutton Blouse looks like an extremely similar shape to this, but is designed for wovens rather than knits. It will be interesting to see it pop up on blogs.
