TanLines - Tan Lines Concept LoRA for Illustrious / SDXL

TanLines — Visible Tan Lines Concept LoRA

Adds realistic visible tan lines to your Illustrious generations. The LoRA teaches clear skin tone contrast between sun-exposed and covered areas — the distinctive pattern left by swimwear. Supports both bikini-style and one-piece swimsuit tan line patterns.

HOW TO USE

Trigger word: tanlines

For best results, combine the trigger word with sub-type tags to control the pattern:

"tanlines, bikini_tan" — classic bikini tan line pattern (triangles on chest, sides of hips)

"tanlines, one-piece_tan" — one-piece swimsuit tan pattern (back, shoulders, full torso contrast)

"tanlines" alone — general tan lines, model decides pattern

The sub-type tags (bikini_tan, one-piece_tan) are the key control mechanism. Use them to get the exact pattern you want.

STRENGTH GUIDE

Lite (0.4-0.6): Subtle tan difference — mild skin tone contrast. Good for realistic, understated tanlines.

Standard (0.6-0.8): Clear tanlines — visible contrast between tanned and untanned skin. The sweet spot.

Full (0.8-1.0): Strong tanlines — very prominent skin tone difference, deep tan with bright untanned areas.

Recommended: 0.8 with sub-type tags for clear, natural-looking tanlines.

WORKS WITH

- Beach, pool, onsen, bath, bedroom, and outdoor scenes

- All hair colors, body types, and skin tones

- Both clothed (tanlines peeking out) and nude (full visibility)

- Solo, couple, and group compositions

- Fantasy, athletic, casual, and intimate scenarios

- Compatible with other LoRAs (styles, characters)

- The tanlines appear wherever skin is exposed — more visible skin = more visible effect

SCENE IDEAS

1. Beach / pool scenes with bikini_tan — classic summer look

2. Onsen / bath scenes with one-piece_tan — full body tanline reveal

3. Undressing / changing scenes — moment of tanline discovery

4. After-swim shower scenes — wet skin highlights the contrast

5. Morning bedroom scenes — intimate tanline visibility

6. Sports / athletic scenes — tanlines peeking through activewear

7. Fantasy characters with tanlines — elves, warriors, mermaids with unexpected tans

TIPS

1. Sub-type tags matter — "bikini_tan" vs "one-piece_tan" gives you different patterns

2. Scenes showing more skin show more tanlines — nude and undressing scenes work best

3. Lighting helps — direct sunlight and bright scenes make the contrast more visible

4. Works great with "tanned" and "dark_skin" tags for deeper overall tan

5. Combine with after_beach, summer, wet tags for context

6. Try different body parts: "tanlines on back", "tanlines on thighs" for focused effect
