# How do I adjust the garment length?

## 1. Product shot: using the 'brush tool'

In photos where only the product is shown alone, the result depends on how the user defines the area with the brush.

* How to use: paint the area where you want to adjust the length with a brush.
* Point: when shortening the length, prompt so that the existing (sleeve) design is preserved. 

{% hint style="info" %}
Shorten the sleeve lengths to end at the top boundary of the purple masked areas, \
while perfectly preserving all original design details of the cuffs. \
Remove the purple masked areas from the final result.
{% endhint %}

## 2. Model shot: using 'body information'

For photos of a model wearing the clothing, adjust the length by using body information such as the model's elbows, knees, and ankles.

* How: use the brush to specify the area where you want to extend the garment length.
* Point: it is more accurate if you write the prompt using body information.

{% hint style="info" %}
Change the dress skirt length to a shorter midi length. \
Edit the image so that the original model's legs are visible, not the skirt in the purple area.\
Remove the purple masked areas from the final result.
{% endhint %}

## 3. Advanced: using design 'reference points' instead of numerical values (cm)

AI cannot calculate physical lengths. Instead, if you write prompts using the clothing's detail points or body landmarks as reference points, you can dramatically reduce errors.

### 3-1. Communicating with a 'design guideline'

Instead of saying "extend it by 5 cm," specify the endpoint where the garment ends in design terms.

| **Adjustment area** | **Designer intent**                          | **Recommended AI prompt (translation)** |
| ------------------- | -------------------------------------------- | --------------------------------------- |
| Sleeve              | Shorten to the wrist bone position           | `End at the wrist bone`                 |
|                     | Extend to cover half of the back of the hand | `Extend to the knuckles`                |
| Top length          | Align with the hip line                      | `Align the hem with the hip bone`       |
|                     | Length covering the buttocks                 | `Length covering the buttocks`          |
| Bottom length       | Adjust to the ankle bone position            | `Crop at the ankle bone`                |
|                     | Length covering the shoes                    | `Full-length, covering the shoes`       |

### 3-2. Using clothing 'details' as reference points

Using elements already built into the clothing as references improves design consistency.

* Pocket reference: "Align the jacket hem with the bottom edge of the side pockets."
* Button reference: "Shorten the length to the position of the bottom button."
* Seam reference: "Raise the sleeve to the height of the elbow seam."

## 4. Recommended prompts for adjusting length by clothing type

Prompt usage formula (Template)

{% hint style="info" %}
\[Verb: Shorten/Extend] the \[part: Sleeve/Waist/Hem] to the boundary of the masked areas, while perfectly preserving all original design details.&#x20;
