Underboob Crop Tops

Tiny crop tops with underboob visibility, styled as modern casual or streetwear rather than lingerie or swimwear.

This LoRA was trained to hold onto one specific thumbnail-readable hook: an extremely short crop top where the hem sits above the navel and the lower curve of the breasts is visible. The goal is not generic attractiveness or generic lingerie. The goal is the abbreviated top silhouette itself — the underboob read must be immediate.

Trigger

• v2: Use ubcr0p in the prompt

• v1: Use underboob_crop in the prompt.

Best Use

• extremely short or micro crop tops

• visible underboob or lower breast curve

• baby tees, ribbed tanks, fitted camisoles cropped very short

• streetwear, apartment, mirror, rooftop, and casual interior settings

• layered looks (open jacket over tiny crop top)

Prompting Notes

• Keep the underboob reveal explicit in the prompt.

• Pair the crop top with low-rise jeans, shorts, or cargo pants so the midriff and underboob stay readable.

• Frontal, mirror selfie, seated/leaning, and street compositions all work well.

• If the render drifts into generic fashion or normal-length crop tops, push underboob, extremely short crop top, visible underboob, and micro top harder.

Variants

• Illustrious XL: strongest concept signal for tag-based workflows

• Klein 9B: calmer realistic branch, natural language

• Z-Image: strongest natural-language branch, modern Lumina architecture

Recommended Starting Weights

• Flux.1 D: 0.9

• Illustrious XL: 0.7

• Klein 9B: 0.8

• Z-Image: 0.8

This release was built from a dedicated underboob-crop-tops-v1 dataset. The concept boundary is narrow: abbreviated top silhouette first, generic sexiness second. Every training image was selected to communicate the underboob concept clearly at thumbnail size.

Curation Note

Rejected from training: bra-only looks, bikini or swimwear images, gymwear, cleavage-focused images with no underboob shape, and oversized shirts that don't read as intentionally tiny tops. The main curation trap is the dataset becoming generic "hot woman in small top" instead of a distinct underboob streetwear concept.
