Key Takeaways
crop top alone is sufficient for midriff exposure. 3/3 showed abdomen exposure; no additional keywords needed.- Adding
bare midriff, navel visible has minimal effect. Since crop top already exposes the navel, these additions are redundant. tied-up shirt offers a different casual feel from crop top. A shirt hem tied in a knot creates a street fashion vibe.- Urban street background (
urban street, bright lighting) pairs well with these styles.

Results by Condition
A00: Crop Top
1girl, 32yo japanese actress, wearing white crop top and jeans, standing, upper body, urban street, bright lighting
Observations: 3/3 reproduced a crop top with visible navel. Combined with jeans for a street casual look. Abdomen exposure is natural, and the crop top specification alone delivers sufficient results.
A01: Bare Midriff Added
1girl, 32yo japanese actress, wearing white crop top and jeans, bare midriff, navel visible, standing, upper body, urban street, bright lighting
Observations: No significant difference from A00. Since the navel is already exposed with the crop top specification, adding bare midriff, navel visible is redundant. Crop top alone is sufficient from a token-efficiency perspective.
A02: Tied-Up Shirt
1girl, 32yo japanese actress, wearing white tied-up shirt and jeans, standing, upper body, urban street, bright lighting
Observations: A shirt with the hem tied in a knot to expose the navel. Unlike crop top, the original long shirt is knotted, giving a more casual, rough vibe. The knot serves as a clothing accent.
Note: The tied-up shirt has a looser feel than crop top, giving it more of a street style, and is a viable alternative choice.
Comparison Summary
| Condition | Navel Exposure | Outfit Impression | Token Efficiency |
|---|
| A00 crop top | 3/3 | Casual | Good |
| A01 bare midriff added | 3/3 | Same as A00 | Redundant |
| A02 tied-up shirt | 3/3 | Rough, street | Good |
