I used the Simplicity 4156 and just modified the collar. The blue stripes on the sleeves felt to "beach ball" for me, so I left those off.
Lesson learned: I should have cut the skirt and bodice polka dot trim to shape instead of cutting bias strips. Getting the bias strips to go around the curves was super time consuming
But eventually I was done and I loved the way it looked!
I used a white fabric paint pen to add white polka dots to the skirt trim where they went missing in the join after this photo was taken.
I had a REALLY good time!
