Character LoRA for Naomi, commision OC, a curvy yoga/fitness instructor with long black hair, purple eyes and a black/purple athletic aesthetic.

The LoRA was trained primarily around her canonical yoga / sportswear appearance, but was also tested successfully in very different environments and outfits including casual streetwear, nighttime city scenes and café settings.


Trigger word: naomiyoga
Recommended LoRA strength: 0.9-1.0

Recommended settings

Tested mainly with Prefect Illustrious XL v8, PlantMilk Walnut and WAI :

Sampler: Euler a
Steps: 28-30
CFG: 5.5-6
Resolution: 832x1216
LoRA strength: 0.9-1.0

Euler a gave the best overall balance of character identity, expressions and flexibility.

DPM++ 2M Karras also works well and tends to produce a slightly cleaner/polished look, but in my tests it sometimes drifted a little more from the character identity.

Basic character prompt

<lora:Yoga_Teacher_Naomi:1.0>, naomiyoga,
1girl, solo,
long black hair, straight hair, blunt bangs, purple eyes,
curvy, voluptuous, wide hips, thick thighs, large breasts

Adding explicit character traits helps keep her appearance consistent when using environments or outfits very different from the training data.

Canon yoga / fitness look

Useful tags:

sports bra, yoga pants, leggings,
black and purple sportswear,
barefoot, yoga mat,
fitness studio, gym,
standing, stretching, kneeling, sitting

Example:

masterpiece, best quality, amazing quality, absurdres,
<lora:Yoga_Teacher_Naomi:1.0>, naomiyoga,
1girl, solo,
long black hair, blunt bangs, purple eyes,
curvy, wide hips, thick thighs, large breasts,
black and purple sports bra, black and purple yoga pants,
barefoot, full body, yoga mat, fitness studio,
looking at viewer, gentle smile, soft lighting

Different outfits / environments

The LoRA can work outside the fitness aesthetic, but it helps to describe the replacement clothing clearly.

Useful examples:

casual streetwear
black jacket
cardigan
turtleneck sweater
jeans
straight-leg pants
sneakers
winter coat
scarf
skirt
dress

Environment tags that tested well:

city street at night
neon lights
wet pavement
night
cinematic lighting
café
coffee shop
warm indoor lighting
city lights
apartment
outdoors
snowfall

If the LoRA keeps pulling clothing back toward sportswear, add unwanted concepts to the negative prompt, for example:

sports bra, yoga pants, leggings, gym wear, sportswear,
fitness studio, yoga mat,
latex, shiny clothes, skin-tight clothes

Face/detail prompting

For full-body images, these can help:

(detailed eyes:1.2),
(beautiful detailed face:1.15),
(purple eyes:1.2),
looking at viewer

The character generally produces more detailed faces naturally in upper-body and portrait compositions.

Suggested negative prompt

bad quality, worst quality, worst detail, lowres, blurry,
blurry face, blurry eyes, poorly drawn face, distorted face,
bad anatomy, bad hands, extra fingers, missing fingers, fused fingers,
bad feet, extra toes, extra limbs, missing limbs, malformed limbs,
bad proportions, duplicate, multiple girls,
red hair, orange hair, brown hair,
text, watermark, signature, artist name

Notes

The training set intentionally emphasizes Naomi's curvy body shape, black/purple palette and yoga-instructor aesthetic, so those characteristics can remain fairly strong even when changing outfits or environments.

For maximum flexibility, describe the desired clothes and scene explicitly rather than relying on broad tags such as casual clothes.

Tested successfully with: gym/yoga scenes, casual clothes, café interiors, nighttime streets and neon lighting.
