Key Takeaways
- Simply adding the wet keyword produces stable see-through effects across all materials. All 4 wet conditions achieved 3/3 see-through reproduction. Regardless of material, the wet keyword’s see-through triggering power is high.
- Transparency differences between materials are small, but texture and garment shape differences are significant. Cotton maintains a crew-neck t-shirt shape, silk transforms into a buttoned blouse with added sheen, and linen reproduces a coarse weave texture.
- Silk specification changes garment shape the most dramatically. Even when specifying t-shirt, it tends to transform into a blouse (collared, front-button) in 3/3 results. The characteristic thin, glossy fabric feel stands out.
- Cotton reproduces the most authentic wet t-shirt look. It maintains the crew-neck, short-sleeve t-shirt shape while the fabric clings to the skin showing underwear through the material. If you want a faithful “wet white t-shirt,” cotton is the right choice.
- Linen has the strongest fabric presence. The coarse weave texture is reproduced, and even when see-through, the fabric quality remains visible.

Base Prompt
1girl, 32yo japanese actress, wearing {CONDITION}, standing, facing camera, upper body, simple white background, soft studio lighting
The {CONDITION} portion is replaced with the following 5 patterns:
| Condition | CONDITION |
|---|
| A00: Control | white t-shirt |
| A01: wet cotton | wet white cotton t-shirt |
| A02: wet silk | wet white silk blouse |
| A03: wet linen | wet white linen shirt |
| A04: wet polyester | wet white polyester shirt |
Evaluation Criteria
The following visual attributes were observed and recorded:
- Transparency: How much underwear and skin show through (opaque / semi-transparent / transparent)
- Garment shape: How material specification affects silhouette and details (collar, buttons, sleeves)
- Texture: Whether material-specific textures (sheen, weave, surface smoothness) are reproduced
- Wet expression: Water droplets, skin-clinging, wet hair
Testing Each Condition
A00: Control (Dry White T-Shirt)
1girl, 32yo japanese actress, wearing white t-shirt, standing, facing camera, upper body, simple white background, soft studio lighting
Observations: 3/3 wearing a white t-shirt, opaque with no see-through. Seed 1 produced a two-person composition within the frame (a seed characteristic that appears in subsequent conditions as well). Seed 2 is the most stable single-person white t-shirt composition. Seed 3 had a butterfly decorative pattern in the background. The crew-neck, short-sleeve t-shirt shape was reproduced in 2/3.
A01: wet white cotton t-shirt
1girl, 32yo japanese actress, wearing wet white cotton t-shirt, standing, facing camera, upper body, simple white background, soft studio lighting
Observations: 3/3 showed the t-shirt becoming see-through with the bra visible underneath. The crew-neck, short-sleeve t-shirt shape is maintained, and as a cotton effect, the casual t-shirt feel is preserved. The wet specification also makes the hair wet and water droplets appear on the skin. Seed 2 has the highest transparency, with the fabric clinging to the skin and the underwear outline clearly visible. Seed 3 has slightly lower transparency, but this may be influenced by the tighter framing reducing the chest area coverage.
A02: wet white silk blouse
1girl, 32yo japanese actress, wearing wet white silk blouse, standing, facing camera, upper body, simple white background, soft studio lighting
Observations: 3/3 showed see-through effects. The most notable change was the garment shape transforming from t-shirt to blouse. The silk blouse specification generated a collared, front-button, long-sleeve blouse in 3/3. A silk-like sheen was added, with light reflections visible on the fabric surface. Seed 2 has the highest transparency, with fabric clinging to the skin and clear underwear outline. Seed 3 has an open chest area, with exposure coming more from the opening than the see-through effect.
A03: wet white linen shirt
1girl, 32yo japanese actress, wearing wet white linen shirt, standing, facing camera, upper body, simple white background, soft studio lighting
Observations: 3/3 showed see-through effects. The distinctive linen characteristic of coarse weave texture was reproduced, with roughness and horizontal/vertical thread patterns visible on the fabric surface. Seeds 1 and 2 show underwear through the material, but compared to cotton and silk, the fabric presence is stronger — an expression of “see-through but still very much fabric.” Seed 2 had curtains appearing in the background. Seed 3 has reduced transparency with an open chest area.
A04: wet white polyester shirt
1girl, 32yo japanese actress, wearing wet white polyester shirt, standing, facing camera, upper body, simple white background, soft studio lighting
Observations: 3/3 showed see-through effects. The polyester specification generated collared shirts, with a surface that’s not as glossy as silk but smoother than linen. Seeds 1 and 2 show underwear through the fabric, but seed 3 has weak transparency with the chest mostly covered by clothing. Overall, the visual difference between silk blouse and polyester shirt is small — the material-level distinction between these two is smaller than between silk-cotton or linen-cotton.
Material Comparison Summary
| Material | See-Through Rate | Garment Shape | Texture Characteristics | Wet Expression |
|---|
| Control (dry) | 0/3 | Crew-neck t-shirt | Opaque, matte fabric | None |
| cotton | 3/3 | Crew-neck t-shirt | Casual, skin-clinging | Hair and skin also get wet |
| silk | 3/3 | Collared blouse | Glossy, thin | Hair and skin also get wet |
| linen | 3/3 | Collared shirt | Coarse weave, strong fabric presence | Hair and skin also get wet |
| polyester | 3/3 | Collared shirt | Smooth, close to silk | Hair and skin also get wet |
Practical Tips
Recommended Materials by Use Case
- Want a “wet white t-shirt” look →
wet white cotton t-shirt. The only option that maintains the t-shirt shape while becoming see-through. - Want elegant wet see-through →
wet white silk blouse. A glossy blouse that’s see-through yet sophisticated. - Want to retain fabric texture →
wet white linen shirt. The weave shows through even when see-through, creating a strong “through-the-fabric” feel. - Want something silk-like but in shirt form →
wet white polyester shirt. Less glossy than silk but smooth.
Notes
- The wet specification makes not just clothing but hair wet too. If you want only the clothes wet, a different approach is needed (to be tested in the future).
- Seed 1 produced a two-person split composition across all conditions. This is a seed characteristic unrelated to material.
- Material names implicitly change the garment type as well. There’s a tendency for cotton = t-shirt, silk = blouse — material and garment shape are interpreted as a set.
