# Style descriptors only. This prompt names no artist, studio, brand or work.

Produce four original images in the visual language of Biker Style, a style from Subculture Style, 1920s–.

## What to make

Make the kind of thing this style exists for: designing leather outerwear for riding protection and mobility, or showing speed, rebellion and group identity through one garment in music, film and fashion. Choose one subject and hold it across all four images.

## What has to be visible

- Asymmetric zipper crossing the front
- Hard outline from wide lapels, epaulettes and waist belt
- Heavy black leather and silver hardware
- Back patches, studs, wear and personal marks

Someone who knows this style should be able to point at each of these in the finished image.

## How to build it

- Layout and structure: Use the diagonal front zip as the main axis and build a triangle through collar, shoulder and belt
- Type and lettering: Align condensed sans or patch lettering with the hardware direction
- Material and surface: Start with heavy black leather, silver zips, snaps and buckles, retaining creases and abrasion from use
- Colour: #DDD8CF carries the ground, #7A1F23 is the colour the style is remembered by, #151515 holds text and outlines. Read off real works, so treat them as a direction rather than a fixed palette.
- What it should feel like: rebellion, exhilaration, trust

## What goes wrong

More black leather and studs do not make the style. Separate riding function from cultural personalization.

## Across the four

Keep every cue above present in all four. Vary the framing, the scale and the arrangement so the set shows the range this style covers rather than four versions of one picture.

## Constraints

- Do not imitate, reference or name any specific artist, studio, brand, character or copyrighted work.
- Do not reproduce the composition of an existing work.
- Produce original compositions in the general period language described above.
