This sweater was once a big sort of long cardigan. I cut an empire seam, easily following the stripe and i turned the front to the back. I had to make two bust pleats at the front bodice and two tucks in the upper back.

In order to fit the back i made princess seams from the empire to the hem.

The center front has a stitchdown inverted pleat also.

Lastly, i made the long sleeves into short ones and reattached the original cuffs.
