Key Takeaways
- School uniform dishevelment prompts are surprisingly weak. Even specifying
loosened tie, rolled-up sleeves, top button undone, a neat uniform may still be generated. - The most obvious change is the presence or absence of the blazer. Specifying
blazer removed switches to a shirt-only look, giving a disheveled impression. loosened tie and rolled-up sleeves work partially. A loosened tie was reproduced in 2/3, but rolled-up sleeves only in about 1/3.disheveled school uniform produces “slightly casual” rather than “messy.” Dramatic dishevelment (shirt wide open, etc.) doesn’t happen.- School hallway background gives very high uniform reproduction fidelity.

Conditions
| Stage | Condition | Key Prompt Elements |
|---|
| 1 | A00: Neat | neat school uniform with blazer and plaid skirt |
| 2 | A01: Light dishevelment | loosened tie, rolled-up sleeves, top button undone |
| 3 | A02: Moderate | blazer removed and carried, shirt untucked, skirt shortened |
| 4 | A03: Full dishevelment | disheveled school uniform, tie loose and askew, cardigan off one shoulder, messy hair |
Results by Condition
A00: Neat
1girl, 32yo japanese actress, wearing neat school uniform with blazer and plaid skirt, standing, facing camera, upper body, school hallway, bright lighting
Observations: In 3/3, a blazer + plaid skirt + shirt + ribbon tie uniform was reproduced in a neat state. Buttons fastened, tie/ribbon properly tied. School hallway background is stable.
A01: Light Dishevelment (loosened tie + rolled sleeves)
1girl, 32yo japanese actress, wearing school uniform, loosened tie, rolled-up sleeves, top button undone, standing, facing camera, upper body, school hallway, bright lighting
Observations: Seed 2 reproduced a blazer-less shirt look with tie and rolled sleeves, showing a disheveled feel. However, in seeds 1 and 3, the shirt buttons remained fastened or sleeves stayed down — stability of the dishevelment specification is moderate. loosened tie worked in 2/3, but rolled-up sleeves is unstable.
A02: Moderate Dishevelment (blazer removed + shirt untucked)
1girl, 32yo japanese actress, wearing school uniform, blazer removed and carried, shirt untucked, skirt shortened, standing, facing camera, upper body, school hallway, bright lighting
Observations: Surprisingly, seed 2 shows a neat blazer-on look with ribbon tie. blazer removed and carried didn’t take effect. shirt untucked reflection is also unstable. The dishevelment specification is losing to the model’s default behavior of “wearing it properly.”
A03: Disheveled (full dishevelment)
1girl, 32yo japanese actress, wearing disheveled school uniform, tie loose and askew, cardigan off one shoulder, messy hair, standing, facing camera, upper body, school hallway, bright lighting
Observations: Even with disheveled specified, no dramatic dishevelment occurs. messy hair works — hair becomes somewhat tousled — but the outfit itself doesn’t get very messy. cardigan off one shoulder shows shoulder-slip effects similar to the Off-Shoulder Variation Test findings, but isn’t stable in the school uniform context.
Note: Disheveling a school uniform tends to be difficult to achieve through prompting. Even a change as small as removing the blazer is hard to reproduce stably.
Comparison Summary
| Stage | Dishevelment Rate | Biggest Change Factor |
|---|
| A00: Neat | 3/3 | Baseline |
| A01: Light dishevelment | 2/3 | Loosened tie + no blazer |
| A02: Moderate | 1/3 | Unstable (reverts to neat) |
| A03: Disheveled | 2/3 | Messy hair is the most stable |
Practical Tips
- Remove the blazer:
school uniform without blazer, shirt only — explicitly stating “no blazer” is likely more stable than blazer removed - Tie state:
loosened tie works but isn’t perfect. Worth trying alternatives like tie pulled loose - Rolled sleeves:
rolled-up sleeves has low stability. The default state (sleeves down) is strongly favored - Messy hair:
messy hair is relatively stable. Effective for creating a disheveled atmosphere
Why Dishevelment Is Hard to Achieve
It’s plausible that “neatly worn” uniforms dominate the model’s training data. Dishevelment and messiness are exceptional states, and prompts specifying them tend to be overridden by the default “neat” state. This shares the same pattern as the weak unbuttoned specification in the Undressing Stage Control Test.
