- Problem area: neck
- Can it be altered: yes

A neckline that gaps or sags looks untidy and can expose more than you intended.

## Likely causes

- The neckline is cut too deep or too wide.
- The neckline edge stretched during stitching or wear.
- No facing, lining or stay tape supports the edge.
- Curved or deep necklines were cut without shaping for the body.

## How it is fixed

- **Add a small dart** at the neckline to remove extra fabric.
- **Stitch stay tape** around the neckline edge to stop it stretching.
- **Add a facing or lining** so the edge lies flat.
- **Reshape the neckline** slightly higher if the design allows.

## Can it be altered?

Usually yes, especially with a dart or stay tape.

## Prevent it next time

Give the front and back neck depth when you order and check the neckline at the trial fitting. See the [blouse design library](/blouse-designs) for necklines and how each is cut.

## Frequently asked questions

### Can a deep neckline be fixed without raising it?

Often yes. A dart or a stay tape can remove the gap and keep the depth.

### Why does my neckline keep stretching?

Curved edges are cut on the bias in places and can stretch. A stay tape or facing prevents this.
