According to Sewing.org, a dart's purpose is to "shape a flat piece of fabric to fit bust, waist, hip or elbow curves." The dart is useful when making clothing more fitted. However, you may find that you may be working with fabric that is fragile or you do not have the time to sew in the darts. It is possible to get the fitted effect without darts.
Lay the pattern out on your work table. Use a ruler to measure the length of the dart. If the pattern is for more than one size, make sure that you measure the dart that corresponds with your size.
Cut open a paper bag so that you have a large piece of paper. Lay it beneath the pattern from which you wish to remove the dart.
Trace around the pattern piece, making sure you record the center front of the pattern, the neckline, the seam of the shoulder, the eye of the arm, the bust eye, the bottom of the pattern or the hem, as well as any notches.
Fold the dart on the pattern. Measure the dart's depth and mark a point that lines up with the center front as well as the hem you traced.
Trace the pattern with the side seam when the dart is folded. Join the mark you made in step 4 with the side seam and also the center front.
Cut out the pattern piece. You now have a new pattern piece that allows you to make the same fitted garment without the dart.
