NaturalBeauty FLUX Nudity is a photorealistic LoRA for creating full-body nude and topless images of beautiful women with the FLUX.1 dev model.
To trigger the LoRA, add naked or topless to your prompt.
This version of NaturalBeauty is the result of a year-long project to tag nearly 12k images using a diverse and flexible dataset.
Tagging
NaturalBeauty FLUX Nudity can do more than just nudity! In addition to naked and topless, try adding any of the following extra details for more control:
{a caucasian|a black|an asian|a latina|an indian} woman,
{standing, wide stance|standing, feet together|kneeling|squatting},
{naked|topless},
{barefoot|high heels}, {short|medium length|long|very long} {braided|braids|crimped|curly|ponytail|straight|wavy} {black|dark brown|medium brown|light brown|brown with blond highlights|chestnut brown|auburn|colored red|bright red|orange red|orange|red|strawberry blond|light blond|medium blond|bleached blond|platinum blond} hair, {neutral expression|slight smile|full smile}, mouth {closed|slightly open|open}, eyes {closed|open}, looking at camera, {tiny|small|medium|large|huge|massive} {fake|natural} breasts, {arms by side|hands behind head|hands by shoulders|hands holding breasts|hands on thighs|hands on hips}
For example:
a caucasian woman, standing, wide stance, naked, long wavy medium blond hair, slight smile, mouth closed, eyes open, looking at camera, small breasts, hands behind head
NaturalBeauty FLUX Nudity is optimized to produce good results without needing a negative prompt.

Notes
This LoRA is a follow-on to a FLUX checkpoint I released back in November 2024, named NaturalBeauty FLUX. Based on feedback from that model, I'm focusing on LoRA rather than checkpoint training. This LoRA is the first result of that
