Natural Breasts — for MOSS Image

A small, focused LoRA for natural breast shape on MOSS-Image. It doesn't inflate the chest, change the face or restyle the image. It makes breasts look real.

What it adds
• Natural sag: real weight, a soft lower curve and a gentle drop instead of a "stuck-on" round shape
• Slight asymmetry: the small left/right differences real bodies have
• Works on any bust size: set the size in your prompt, the LoRA handles the shape
• Reads both topless and under thin fabric (tank tops, knits, shirts)

How to use
• No trigger word. Just load the LoRA.
• Weight: 0.8–1.0 (start at 0.9). Lower it if the bust gets fuller than you want.
• Describe the size in plain words: small / medium / large / very large natural breasts
• Avoid shape words that fight it (perky, pushed-up, round high-set) in the positive. For a fuller look, put small breasts, flat chest in the negative.
• Plays nicely with realism and body LoRAs. Our showcase stack: nicegirls, UltraReal at 0.6, TJ Film, plus our Weight and Waist sliders.

Recommended settings
Euler / simple, 50 steps, CFG 3, SLG layer 22 (0–0.5), 1–2 MP.

Training
• Base: MOSS-Image SFT
• Chest-only training masks with low weight elsewhere, so poses, rooms and lighting don't bleed in
• Detailed MOSS-style captions describing everything except breast shape
• Rank 8, differential guidance, 1000 steps

Version notes
v1 is the fifth training run. Earlier runs either overfit into one look or pulled the shape too round, or the hands started to break. This one keeps hands, faces and poses intact while adding the shape.

Note: no faces from the training data are reproduced. Showcase images use no character LoRA.
