Key Takeaways
- Completely preventing wet keywords from affecting hair is difficult. Even adding
dry hairor targeting only clothing withwet clothing, hair remains wet (3/3 show damp hair). splashed with waterhas the most reduction effect. In 2/3, hair wetness was lower than other conditions, showing improvement. However, completely dry hair was not achieved.- wet specification tends to trigger text artifacts (magazine-style logos, etc.). Particularly noticeable in the control condition.
- If you only want wet/see-through clothing, using
see-throughorsheerinstead of wet is more practical. This completely avoids hair spillover.

Base Prompt
Base Prompt
1girl, 32yo japanese actress, {clothing specification}, standing, facing camera, upper body, simple white background, soft studio lighting
Evaluation Criteria
- Hair wetness: Whether hair is dry, damp, or soaking wet
- Clothing wetness/transparency: Whether the t-shirt is wet and see-through
- Text artifacts: Whether magazine-style text appears in the image
- Side effects on subject: Impact on pose, expression, and composition
Testing Each Condition
A00: wet (Control)
Prompt
1girl, 32yo japanese actress, wearing wet white t-shirt, standing, facing camera, upper body, simple white background, soft studio lighting
| seed 1 | seed 2 | seed 3 |
|---|---|---|
 |  |  |
Observations: In 3/3, hair is soaking wet. The t-shirt is wet and clinging to the skin, with the bra showing through. Text artifacts (gravure magazine-style logos/text) appeared in 2/3, suggesting the wet keyword triggers a gravure photography context. Hair clings to the face and shoulders.
A01: wet + dry hair
Prompt
1girl, 32yo japanese actress, wearing wet white t-shirt, dry hair, standing, facing camera, upper body, simple white background, soft studio lighting
| seed 1 | seed 2 | seed 3 |
|---|---|---|
 |  |  |
Observations: Despite adding
dry hair, hair remains wet in 3/3. The wet influence overpowers the dry hair specification. T-shirt transparency is maintained, with no change to the clothing effect. The dry hair addition had no effect on hair dryness.A02: wet clothing + dry hair
Prompt
1girl, 32yo japanese actress, wet clothing, dry hair, long straight hair, wearing white t-shirt, standing, facing camera, upper body, simple white background, soft studio lighting
| seed 1 | seed 2 | seed 3 |
|---|---|---|
 |  |  |
Observations: Attempted to target only clothing with
wet clothing and protect hair with dry hair, long straight hair, but hair is still damp in 3/3. Completely dry hair was not achieved. Adding long straight hair does tend toward straight hair, but the wet feel persists. The concept of “wet” appears to spill over to the entire scene, making target limitation difficult.Lab Director Comment: “wet clothing” literally means “only the clothes are wet,” right? And yet the hair gets caught in the crossfire. In prompt world, wet is apparently airborne. Can’t complain about the look, but the lack of control is annoying.
A03: splashed with water
Prompt
1girl, 32yo japanese actress, wearing white t-shirt splashed with water, dry hair, standing, facing camera, upper body, simple white background, soft studio lighting
| seed 1 | seed 2 | seed 3 |
|---|---|---|
 |  |  |
Observations: Using
splashed with water for a “water was thrown on it” expression showed some improvement. In 2/3, hair wetness was lower than other conditions, with just some water droplets at the tips. However, 1/3 still showed overall damp hair, so completely dry hair was not achieved. splashed with water implies a momentary splash rather than full-body soaking, so hair spillover is smaller compared to wet.Comparison Summary
| Condition | Clothing Wet/Transparent | Hair Wetness | Text Artifacts | Overall |
|---|---|---|---|---|
| A00: wet | Transparent 3/3 | Soaking (3/3) | 2/3 | Everything gets wet |
| A01: wet + dry hair | Transparent 3/3 | Still wet (3/3) | 1/3 | dry hair ineffective |
| A02: wet clothing + dry hair | Transparent 3/3 | Damp (3/3) | 0/3 | Target limitation fails |
| A03: splashed with water | Transparent 2/3 | Somewhat reduced (2/3) | 0/3 | Best improvement but imperfect |
Practical Tips
splashed with waterhas the least hair spillover. Less hair wetness than wet or wet clothing (improvement confirmed in 2/3).- If clothing transparency is your only goal, skip wet entirely and use
see-through white t-shirtorsheer white t-shirt. This completely avoids hair spillover. - wet-related keywords tend to trigger text artifacts. The gravure photography context they invoke can introduce magazine-style text.
- To maintain hairstyle, add hair style specifications like
long straight hair. The wet feel remains, but it can somewhat prevent hair from losing its shape.
