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

Produce four original images in the visual language of Op Art Fashion, a style from Fashion History, 1964–late 1960s.

## What to make

Make the kind of thing this style exists for: using body movement to produce stronger optical effects than a still image in performance or photography, or making a 1960s fashion statement legible at distance with few colors and a simple pattern. Choose one subject and hold it across all four images.

## What has to be visible

- High-contrast black-and-white lines, grids, waves and concentric forms
- Geometry repeated finely enough to unsettle the eye
- Simple shift silhouettes that leave patterns unbroken
- All-over prints whose distortion changes with walking and body curvature

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 a straight form with few seams and carry the optical period uninterrupted from chest to hem
- Type and lettering: Set a heavy sans in a plain band so it does not compete with the pattern frequency
- Material and surface: Vary line width and spacing in two high-contrast colors, then fit-test how stretch and curvature alter the effect
- Colour: #F4F2EA carries the ground, #E53B37 is the colour the style is remembered by, #111111 holds text and outlines. Read off real works, so treat them as a direction rather than a fixed palette.
- What it should feel like: exhilaration, play, technique

## What goes wrong

Not every geometric print is Op Art. The structure must create perceptual vibration, expansion or depth.

## 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.
