Most knitting patterns do not include bust darts. Many knitters simply rely on the stretch of the knitted fabric.
BUT . . . Simply adding a few rows of knitting to the center front of your sweaters will add comfort and allow your sweaters to hang parallel to the floor.
Unlike adding rows for a rounded back or tummy, darts are positioned to point to the fullest part of the bust, adding length and shape to a sweater.

Knit it Now Dynamic Patterns include a link to a tool to help you add bust darts. Watch how it's done.

Use the Knit it Now Tool to calculate your Bust Dart Shaping

Add bust dart shaping to your mylar to be used with a charting device.

Draw the front piece as desired (without darts)
Determine the positioning and depth of your dart
Add the dart to the mylar (just draw a line)
When you reach the start of the dart, note the row counter
Use the Knit it Now Dart Tool (the magic formula or graph paper) to determine the knitting instructions
Pause the charting device
Work the dart(s) with short row shaping
Finish by knitting 1 row across all held needles
RESET YOUR ROW COUNTER to the count before starting the dart
Continue knitting the front

NOTE: Remember you are adding length (rows) to the center of the front piece, but not to the side seams. When done, the row counter should match the row count for the back of your knitting.
