Add a Bust Dart to a Sewing Pattern

Adjust the front bodice pattern so your garment fits, whatever your bust size.

In this video, Louise Cutting shows how to alter a dartless pattern for a blouse to include a side bust dart. This adaptation is important for a smooth, flattering fit on any figure with a bust-cup size of B or larger. It eliminates gaping or strain lines at the center front and keeps the front hemline from rising and flaring out. Louise demonstrates how to take the necessary body measurements and transfer them to the original dart-less pattern. By cutting and spreading the pattern horizontally and vertically, she adds the width and length needed to accommodate the bust fullness.

    I am a G cup, so wondering if we continue up in increments until we get to the correct size, or are we limited to increase?
