About this LoRA

Krea 2 ties bust effects (shaping) to specific garments: centered cleavage comes with push-up bras, compression with sports bras, a shelf effect with corsets. Often the result doesn't even look realistic. This LoRA clearly improves the lifelike effects these garments have on breasts, and it tries (more or less successfully) to separate those effects from the garment. Shaping and cleavage are trained as two independent attributes, so you can combine them freely with the clothing of your choice.

What's new in V2

• Training data doubled, captions reworked and hand-labelled for the trained attributes.

• New cleavage option narrow cleavage between open and centered. Cleavage is now defined by what is visible (skin versus crease) instead of by distance, so it no longer depends on breast size.

• Breast size is now trained as a tag (small/medium/large breasts) instead of relying on sliders alone. Sliders still work on top.

• Optional tags renamed for consistency. V1 prompts keep working with the old LoRA. See the V1 section at the bottom.

Notes

• Garment choice still matters. Although shaping works across garments, a garment that fits the effect helps the model get the right result.

• Effects can be toned with words like "slightly" or "strongly", e.g. strongly centered cleavage.

• Combinable with breast size sliders.

• LoRA strength adjusts the result. Strengths from 0.6 to 1.8 have been tested.

• Enjoy ;)

How to prompt

Pick one shaping tag, one cleavage tag and one size tag, then describe the garment. Optional tags can be added after that.

Example: shelf-lifted bust, centered cleavage, medium breasts, a black satin overbust corset with a sweetheart neckline...

Bust shaping options

• natural bust: not lifted, flattened or pressed. Typical garments: bralette, soft triangle bikini, T-shirt, loose tube top.

• cup-lifted bust: each breast lifted in its own cup, lower curves shaped. Typical garments: push-up bra, balconette bra, underwire bikini, corset with cups.

• shelf-lifted bust: pushed up as one mass by a rigid panel, swell above a flat front. Typical garments: overbust corset, 18th-century stays, corset dress.

• side-pressed bust: pushed inward from the sides, no lift. Typical garments: taut triangle bikini, criss-cross wrap bikini, bandeau with center twist.

• flattened bust: pressed flat from the front, reduced projection. Typical garments: sports bra, binder, Tudor stays, minimizer bra.

Cleavage options

• no cleavage: neckline low enough to show it, but no line or channel.

• open cleavage: a V or U opening, skin visible on both inner curves.

• narrow cleavage: a slot, inner curves close to parallel, a thin strip of skin, mostly shadow.

• centered cleavage: a seam, no skin between, just a dark crease.

If the neckline is too high to show cleavage, leave the cleavage tag out.

Breast size

small breasts, medium breasts, large breasts.

Optional tags

• breasts spilling over the neckline: tissue rises above the top edge.

• breasts spilling at the sides: tissue rises past the side edge.

• breasts spilling out between the cups: tissue pushes through the gap between the cups.

• breasts bulging over the neckline / breasts bulging at the sides: the edge visibly cuts in, with a crease and swell past it. Stronger than spilling, and mostly works with larger sizes.

• underboob: lower curve shows below the garment.

• breasts pressed together by her hands / by her arms: hands or arms visibly push the breasts inward.

⚠️ Some checkpoints tend to render breasts bare whenever breasts are mentioned in the prompt, including through the size or optional tags. If that happens: increase the LoRA strength or leave the size tag out and use a breast size slider instead.

V1 tags (for the earlier version)

The V1 LoRA uses this set. Shaping and the optional-tag concepts are the same; the wording differs.

• Shaping: identical to V2.

• Cleavage: no cleavage, open cleavage, centered cleavage (centered meaning touching or nearly touching). No narrow cleavage.

• Size: not trained. Use the breast size sliders, e.g. medium bust size.

• Optional: spilling over the neckline, spilling at the sides, underboob, hands/arms pressing the bust together.

• Example: shelf-lifted bust, centered cleavage, medium bust size. A black satin overbust corset with a sweetheart neckline...
