Thank you for your prompt reply! However, I cannot pin the darts on myself.
How can I measure and pin them to get an approximate fit before trying them on.
Thanks
Millie
If you don’t have someone to help you pin, put a shirt on and pull it as tight as you would like the new fit. Measure how much you want to take the shirt in. For example, if you measure 3 inches of excess doubled fabric, you will want darts totaling 6 inches.
Depending on the type of fit you want, divide the 6 inches for the front and back darts. Usually back darts are narrower for women. So let’s say, you want 2 inches of darted fabric in the back and 4 in the front.
