Here is an example of pattern alteration options on the Sorbetto from Colette Patterns. It is a great free pattern that you can download here. I choose a polka dot poly chiffon and a navy solid chiffon to create a color blocked look. I also eliminated the bust dart by adding princess seams. The process of pattern alteration is fairly painless and all you need is some tape, pattern paper, ruler, and paper scissors.Take your blouse front & Back pieces and draw the princess seam line. To find this on the front I drew a line from the dart point to the center of the armhole. From there I drew a curve that went about .75 inches from the line. From the dart point to the hem, draw a line that is parallel to center front. I measured the distance the front princess seam was from the side seam and duplicated it on the back pattern.
Also to get the center band simply cut it off and add seam allowance.
To eliminate the bust dart, cut down one dart leg and pivot the dart intake to the princess line. Then using your french curve if you have one, smooth out the seam line. Add seam allowance to princess seam only.
For the back, simply cut up the princess seam to separate the pieces and add seam allowance to both pattern pieces.
True your seams. This means to measure the length of the seams you are sewing together to make sure they will fit perfectly.
This is what all your pattern pieces will look like when finished.
