Key Takeaways
tightandform-fittingproduce nearly identical results. Both create a body-hugging silhouette, but dramatic “tension” is hard to achieve.straining against chesttriggers a garment-pulling action. It tends to produce compositions where the subject grips the chest area of the T-shirt, creating a “fabric about to tear” effect.- Combining body-type modifiers (e.g., large breasts) with tension keywords may be more effective for expressing “tension” in a white T-shirt. Clothing modifiers alone have their limits.

| Model | z-image-turbo (6B, photorealistic distilled) |
| Steps | 8 |
| CFG | 1.0 |
| Size | 1024x1024 |
| Seeds | 3 fixed (shared across all conditions) |
| Per condition | 3 images (3 seeds) |
| Total | 4 conditions x 3 = 12 images |
Testing Each Condition
A00: Control
Prompt
1girl, 32yo japanese actress, wearing white t-shirt, standing, facing camera, upper body, simple white background, soft studio lighting
| seed 1 | seed 2 | seed 3 |
|---|---|---|
 |  |  |
A01: tight
Prompt
1girl, 32yo japanese actress, wearing tight white t-shirt, standing, facing camera, upper body, simple white background, soft studio lighting
| seed 1 | seed 2 | seed 3 |
|---|---|---|
 |  |  |
Observation: The T-shirt fits slightly closer to the body compared to the control, but the difference is minimal.
A02: form-fitting
Prompt
1girl, 32yo japanese actress, wearing form-fitting white t-shirt, standing, facing camera, upper body, simple white background, soft studio lighting
| seed 1 | seed 2 | seed 3 |
|---|---|---|
 |  |  |
Observation: Nearly identical to tight. Both form-fitting and tight create a body-hugging silhouette, but the difference between them is minimal.
A03: straining
Prompt
1girl, 32yo japanese actress, wearing white t-shirt straining against chest, standing, facing camera, upper body, simple white background, soft studio lighting
| seed 1 | seed 2 | seed 3 |
|---|---|---|
 |  |  |
Observation: In 2/3 images, a garment-pulling action appeared. In seed 2, the subject grips the chest area of the T-shirt with both hands, creating visible fabric tension. straining against triggers a dynamic “fabric under stress” expression rather than just a fitted look.
Note: Straining tends to induce an action of pulling at the clothing, offering a different approach from tight/form-fitting.
Practical Tips
- For a body-hugging fit:
tightorform-fitting(nearly identical, 1-2 tokens) - For visible fabric tension:
straining against chest— dynamic tension effect - No meaningful difference between
tightandform-fitting. Either one will do
