We had a fabulous #PatternPuzzle conversation last Saturday with four different players contributing to the solution of a complicated style. This pattern shape is the front and back dress as one pattern piece for the body of the Jersey Ruche Dress. The sketch below illustrates ruching in the shoulder line and down the right hand side of the dress. Also note the sleeves have different treatment for the right and left side. The right sleeve is a raglan style that includes the shoulder piece. And the left sleeve is the regular set-in sleeve.
You'll find all the pattern making instructions on the website blog.
