Key Takeaways
rainalone does not wet the clothing. Road surfaces and backgrounds show rain effects, but clothing and skin remain dry. To achieve wet see-through,soaking wet+drenchedmust be added.- Transparency varies clearly by outfit type. White sundress > blouse > T-shirt in order of transparency. Fabric thinness and body adhesion determine the transparency level.
- White sundress is the most transparent. Thin fabric clings to the entire body, with underwear lines and skin color clearly visible. Rain depiction also tends to be the most intense.
- Rainy outdoor scenes have high composition stability. Similar to gym backgrounds, single-person compositions are stable, with street scenery, road reflections, and rain streaks naturally rendered.

Base Prompt
Prompts differ by condition, so each is listed individually.
| Condition | Outfit | Wet Modifier |
|---|---|---|
| A00: rain (control) | white t-shirt and jeans | rain only |
| A01: soaking wet T-shirt | soaking wet white t-shirt and jeans | heavy rain, drenched |
| A02: soaking wet blouse | soaking wet white blouse and skirt | heavy rain, drenched |
| A03: soaking wet sundress | soaking wet white sundress | heavy rain, drenched |
Evaluation Criteria
- Transparency: How much underwear or skin shows through?
- Wet expression naturalness: Does it look natural as a rainy situation?
- Fabric adhesion: How much does the fabric cling to the body?
- Rain depiction: Rain streaks, road reflections, water droplets
Results by Condition
A00: rain (no wet modifier)
| seed 1 | seed 2 | seed 3 |
|---|---|---|
 |  |  |
Observations: In 3/3, city street background with white T-shirt and jeans. The road surface is wet, conveying the rainy situation, but the clothing remains dry with no see-through. rain alone affects weather/background but has limited power to change clothing state.
A01: soaking wet white T-shirt
| seed 1 | seed 2 | seed 3 |
|---|---|---|
 |  |  |
Observations: In 3/3, the white T-shirt is wet and clinging to the skin. Transparency is moderate — underwear outlines are faintly visible. Hair is also soaking wet, plastered to the face. Rain streaks appear in the frame, and road surface reflections with puddles are visible. The difference from the control (A00) is stark. Seed 1 shifts to a full-body composition with the jeans also showing a wet color tone.
A02: soaking wet white blouse
| seed 1 | seed 2 | seed 3 |
|---|---|---|
 |  |  |
Observations: In 3/3, the white blouse is see-through with underwear clearly visible. Higher transparency than the T-shirt (A01). The blouse’s thin fabric clings to the skin in the rain, with the bra’s color and shape clearly showing through. The collared blouse shape is maintained while being transparent, similar to the silk blouse result in the Material-Based Wet Clothes Test. The white skirt also shows some transparency in the lower body.
A03: soaking wet white sundress
| seed 1 | seed 2 | seed 3 |
|---|---|---|
 |  |  |
Observations: The highest transparency across all 3/3. The thin white sundress fabric clings to the entire body, with underwear lines and skin color clearly showing through. Seeds 1 and 2 are particularly impressive — standing in heavy rain with the fabric plastered to the body. Rain depiction is also the most intense of the 4 conditions, with background bokeh and road reflections creating a cinematic atmosphere. The sundress’s characteristically thin fabric covering a large area maximizes the see-through surface when wet.
🗨️ Lab Director: White sundress in the rain — straight out of a movie scene. It’s wild how the see-through ends up being more emotional than explicit.
Comparison Summary
| Outfit | See-Through Rate | Transparency | Adhesion | Rain Depiction |
|---|---|---|---|---|
| T-shirt (rain only) | 0/3 | None | None | Road surface only |
| T-shirt (soaking wet) | 3/3 | Medium | Medium | Rain streaks |
| Blouse (soaking wet) | 3/3 | High | High | Rain streaks |
| Sundress (soaking wet) | 3/3 | Highest | Highest | Most intense |
Practical Tips
Keyword Composition for Wet See-Through in Rain
Minimum required elements:
- Add
soaking wetbefore the garment name — wet alone works, but soaking wet is more reliable - Add
heavy rainto the background description — rain alone doesn’t wet the clothing - Add
drenched— emphasizes a completely drenched state
Controlling Transparency
- Maximum transparency →
soaking wet white sundress. Thin fabric provides see-through over a large area - Medium transparency →
soaking wet white blouse. Underwear visible but fabric shape maintained - Subtle transparency →
soaking wet white t-shirt. Cotton thickness slightly reduces transparency
Comparison with Material-Based Test
The Material-Based Wet Clothes Test compared wet + material name in a studio background. Differences from this rain scene:
- Studio background (wet) → Clothing and hair get wet, but no rain streaks or water droplet depiction. Elegant wetness
- Rain scene (soaking wet + heavy rain) → More dramatic wetness. Rain streaks and road reflections add situational credibility
🗨️ Lab Director: Rain x white sundress is an absolute classic. But this might be pushing it for a thumbnail… borderline.
