![[Experiment] Naked Apron Prompts — Output Differences Between naked apron vs nude apron, and Angle-by-Angle Reproduction](/tips/naked-apron-test/B_seed42_0_0000_42.webp)
Conclusion
- naked apron / nude apron / wearing only an apron all produce equivalent naked apron results
- “apron” alone does not produce a naked apron (normal clothes + apron instead). naked/nude modifier is required
- The back angle (from behind) most effectively expresses the naked apron aesthetic
- Design specifications like frills are reflected while maintaining the naked apron state
- Kitchen backgrounds are consistently generated as specified

Base Prompt
Kitchen is used as a consistent background for all conditions.
Condition A: naked apron + front (2 tokens)
The most common naked apron expression.
Observations
Front-facing images wearing an apron. The naked apron state (no clothing beneath the apron) is reproduced. Kitchen backgrounds feature pots and cooking utensils.
Condition B: naked apron + back (2 tokens)
Back angle that most effectively expresses the naked apron aesthetic.
Observations
Back angle depicting the characteristic elements of a naked apron. The entire back is exposed with apron strings tied behind. The waist-to-hip line is visible. Kitchen backgrounds are consistently generated across all 3 images.
Condition C: nude apron + front (2 tokens)
Using nude instead of naked.
Observations
Nearly identical output to A. No visual difference confirmed between “nude apron” and “naked apron.”
Condition D: wearing only an apron + front (5 tokens)
Natural language description.
Observations
Same naked apron state as A/C. Natural language description produces equivalent results.
Condition E: apron only (1 token)
A comparison case using just “apron” — does it produce normal clothes + apron?
Observations
An apron is worn, but normal clothing (t-shirt, etc.) is underneath. Without “naked/nude,” the naked apron state is not produced — instead, a normal “person wearing an apron” is generated.
Condition F: naked apron + frilled (4 tokens)
Testing with apron design specification.
Observations
Naked apron with frilled apron. The apron has frills and lace decorations. Naked apron state is maintained.
Cross-Comparison
Keyword Comparison, Front (naked apron / nude apron / wearing only / apron only)
| Seed | naked apron (A) | nude apron (C) | wearing only (D) | apron only (E) |
|---|---|---|---|---|
| 42 | | | | |
| 123 | | | | |
| 789 | | | | |
A/C/D all produce equivalent naked aprons. Only E produces normal clothes + apron — the naked/nude modifier is essential.
Angle and Design Comparison (front / back / frilled)
| Seed | Front (A) | Back (B) | Frilled (F) |
|---|---|---|---|
| 42 | | | |
| 123 | | | |
| 789 | | | |
The back angle (B) most effectively expresses the naked apron aesthetic. The frilled version (F) reflects the design specification.
Key Findings
Keyword Comparison
- naked apron / nude apron / wearing only an apron all produce equivalent naked apron results — no practical difference between keywords
- “apron” alone does not produce a naked apron. Normal clothes + apron are generated, so the naked/nude modifier is essential
Angle-by-Angle Reproduction
- The back angle (from behind) most effectively expresses the naked apron aesthetic. Back exposure, apron strings, and visible hip line are depicted
- The front angle also reproduces the naked apron state, but the apron covers the front of the body, so exposed area is less than the back
Design Specifications
- Design specifications like frills are reflected while maintaining the naked apron state
- Kitchen backgrounds are consistently generated across all conditions
Recommended Prompts
- Minimal:
naked apron(2 tokens) is sufficient - Maximum effect from back angle:
naked apron, from behind, looking back
