![[Experiment] Reverse Bunny Outfit Prompt Verification — Can AI Reproduce the 'Inverted Coverage' Concept?](/tips/reverse-bunny-test/C_seed42_0_0000_42.webp)
Conclusion
- The
reverse bunnykeyword alone does not convey the reverse bunny concept (a standard bunny is generated) - Detailed structural description (Condition C) can reproduce the reverse bunny. Explicit description of bare chest, bare stomach, bolero sleeves, thigh-high stockings, etc. is required
- Heart pasties specification (Condition E) also achieves the reverse bunny-style exposure pattern
- Reproducing a reverse bunny requires explicitly describing “what is exposed and what is covered”
- The keyword “reverse” is not learned by the model as meaning inversion of an outfit
- Color variations (white, pink) are stably reflected, but the latex specification tends to add underwear elements
- Back angle (from behind) succeeded in 2 out of 3 images. Looking-back pose is also reproduced

What Is a Reverse Bunny?
A standard bunny girl outfit covers the body (chest to waist) and exposes the hands and feet. A reverse bunny inverts what is covered — arms and legs (long sleeves, tights) are covered, while the chest, belly, and groin are exposed. Decorative elements like rabbit ears and a bow tie remain.
| Part | Standard bunny | Reverse bunny |
|---|---|---|
| Chest to belly | Covered by leotard | Exposed |
| Groin | Covered by leotard | Exposed (sometimes hidden with pasties) |
| Arms | Bare arms (cuffs only) | Covered with long sleeves / bolero |
| Legs | Pantyhose (see-through) | Covered with knee-highs / thigh-highs |
| Ears, bow tie | Present | Present |

Base Prompt
Condition A: reverse bunny (2 tokens)
Direct name specification. Checking whether the model has learned this concept.
Observations
A standard bunny girl outfit (black leotard, ears, bow tie, cuffs) is generated, and the reverse bunny concept is not understood. The outfit covers the torso, equivalent to a standard bunny.
Condition B: reverse bunny outfit (3 tokens)
Adding “outfit” to the expression.
Observations
Same standard bunny girl outfit as A. Even “reverse bunny outfit” does not reproduce the reverse bunny concept.
Condition C: Bolero Sleeve Type Structural Description
An approach that explicitly states the reverse bunny’s “coverage pattern” with specific structural description.
Observations
The chest, belly, and groin are exposed; black bolero sleeves cover both arms; black thigh-high stockings cover the legs. Black ears, bow tie, and white collar are also depicted. Output matching the reverse bunny definition (arms and legs covered, torso exposed) was achieved.
Condition D: Latex Type Structural Description
A reverse bunny expression centered on latex material.
Observations
A latex material leotard-type outfit with a long sleeve on one arm, but the torso is covered by the leotard. Arm coverage is achieved but torso exposure is insufficient. Pink thigh-highs appear.
Condition E: With Pasties (Heart Pasties)
A style with minimum coverage using pasties.
Observations
Heart-shaped nipple covers (pasties) minimally cover the chest, with necktie, white collar, and cuff decorative elements remaining. Pink thong and thigh-highs minimally cover the lower body. The torso is fully exposed, matching the reverse bunny definition.
Condition F: Normal Bunny Baseline for Comparison
Generating a standard bunny girl under the same conditions for comparison with conditions A–E.
Observations
Standard bunny girl (black satin leotard, ears, bow tie, cuffs, pantyhose). Comparison baseline.
Condition G: Bolero Sleeve Type + Latex Material
Based on Condition C with shiny latex material added. Checking how latex material affects the reverse bunny outfit parts.
Observations
All 3 images reflect latex gloss on the bolero sleeves. However, possibly because the latex material specification strengthened the “costume” interpretation, all 3 out of 3 images had string-like black fabric/underwear elements added near the groin. The groin area that was fully exposed in Condition C now has fabric appearing, suggesting a tendency for latex specifications to attract costume elements. The rabbit ears also take on a latex texture.
Lab Director Comment: Why does adding latex instantly put fabric on the groin? Seems like the material spec is attracting costume elements.
Condition H: Bolero Sleeve Type + White Color Variation
Changing all black parts in Condition C to white. Verifying the stability of color changes.
Observations
All 3 images consistently output white rabbit ears, white bow tie, white bolero sleeves, and white thigh-high stockings. The reverse bunny structure (chest, belly, groin exposed + arms and legs covered) is correctly reproduced the same as Condition C. Unlike Condition G, no extra fabric was added to the groin. The white gives a clean, fresh impression, with a very different atmosphere from the black Condition C.
Lab Director Comment: White reverse bunny, oh wow, love it. Has a kind of wedding vibe, and it’s just a completely different atmosphere from the black one.
Condition I: Bolero Sleeve Type + Pink Color Variation
Changing all black parts in Condition C to pink.
Observations
All 3 images reflected pink rabbit ears, bow tie, bolero sleeves, and thigh-high stockings as intended. The rabbit ears are satin-textured pink, with sleeves and stockings also pink. The white collar is maintained. Reverse bunny structure is stably reproduced. Like white (Condition H), no extra fabric was added.
Condition J: Bolero Sleeve Type + Back Angle
Changing the angle in Condition C to from behind, looking back. Verifying reverse bunny reproducibility from the back angle.
Observations
Seed 42 and seed 123 successfully achieved a back-facing pose with a looking-back composition. The exposed back is visible, and bolero sleeves and thigh-high stockings can be confirmed. Seed 789 produced a more front-facing composition, with the from behind instruction partially ignored (2 out of 3 images succeeded with the back angle). Even from the back, the bolero sleeve structure is maintained, and the reverse bunny concept of “arms and legs covered, torso exposed” can be confirmed from the back as well.
Cross-Comparison
All Conditions Comparison (Name specification → Structural description → Standard bunny)
| Seed | reverse bunny (A) | reverse outfit (B) | Structural (C) | Latex (D) | Pasties (E) | Standard bunny (F) |
|---|---|---|---|---|---|---|
| 42 | | | | | | |
| 123 | | | | | | |
| 789 | | | | | | |
A/B is equivalent to standard bunny (F) — reverse bunny not achieved. C/E achieved reverse bunny torso exposure success. D is partial success.
Color/Material Variation Comparison (Conditions C / G / H / I)
| Seed | Black/Basic (C) | Black/Latex (G) | White (H) | Pink (I) |
|---|---|---|---|---|
| 42 | | | | |
| 123 | | | | |
| 789 | | | | |
- Color changes (H/I) are stable. All 3 images maintain the intended color and reverse bunny structure
- Adding latex (G) reflects gloss, but has the side effect of fabric being added to the groin (all 3 out of 3)
- Color changes alone have no adverse effect on the structure, but material changes carry the risk of attracting costume elements
Key Findings
Name Specification vs. Structural Description
- “reverse bunny” and “reverse bunny outfit” generate standard bunnies. The model has not learned this concept
- Specific structural description (Condition C) succeeded in reproducing the reverse bunny. Explicit descriptions like bare chest, bare stomach, bolero sleeves are effective
Points for Reproducing a Reverse Bunny
- Explicitly specify what to expose (bare chest, bare stomach, exposed torso)
- Specifically specify what to cover (bolero sleeves, thigh-high stockings)
- The conceptual modifier “reverse” does not get through to the model
Reverse Bunny Reproduction Rate by Condition
- Conditions A/B: Failed (standard bunny generated)
- Condition C: Success (reverse bunny structure of bolero sleeves + exposed torso reproduced)
- Condition D: Partial success (latex leotard covers the torso)
- Condition E: Success (heart pasties for minimum coverage, full torso exposed)
- Condition G: Success but with side effects (latex gloss reflected, but fabric added to groin)
- Condition H: Success (reverse bunny structure stably reproduced in white)
- Condition I: Success (reverse bunny structure stably reproduced in pink)
- Condition J: 2 out of 3 successful (reverse bunny structure maintained even from back angle)
Color/Material Variation Findings
- Color changes are safe. Changing black → white or black → pink does not affect the reverse bunny structure
- Material changes require caution. Adding
shiny latex materialreflects gloss but carries the side effect of attracting costume elements (underwear/fabric) - When you only want to change colors, you can just bulk-replace the color specification for each part (
black→white/pink, etc.)
Recommended Prompts
- For stable reverse bunny output, Condition C (structural description type) is most reliable
- For a sexier direction, Condition E (heart pasties type) is effective
- Color variations can be stably achieved with bulk replacement of color names
- Adding materials like latex may disrupt the structure, so proceed with caution
- Back angles mostly succeed with
from behind, looking backbut are not perfect - The key is not to rely on the “reverse” keyword, but to describe the specific costume structure
