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

When the back of a blouse stands away from the body, it looks untidy and can slip off the shoulder.

## Likely causes

- The back neck is cut too wide or too deep.
- The back width is too generous for your shoulders.
- A deep back opening is not shaped to your back curve.
- The fabric has stretched or relaxed with wear.

## How it is fixed

- **Take in the centre back seam** or add a back dart.
- **Reshape the back neckline** and add a facing or lining so it lies flat.
- **Add an inner support strip** or a fixed hook on deep backs.

## Can it be altered?

Usually yes. Taking a blouse in is easier than letting it out, so back gaping is one of the more straightforward fixes.

## Prevent it next time

Give the back neck depth and shoulder width when you order, and check the back in the trial fitting. See [how to measure for a blouse at home](/guides/how-to-measure-for-a-blouse-at-home).

## Frequently asked questions

### Can back gaping be fixed without changing the design?

Often yes. A small dart or a refined neckline can be added without changing the look.

### Why does my deep back blouse keep slipping?

Deep backs need a shaped fit and sometimes lining or a support tape to hold against the body.
