How to show fabric texture and fit in AI photos
Name the fabric the way a mill would (weave or knit, weight, finish, sheen), light it from a low side angle so the texture casts small shadows, and add one macro close-up. For fit, use the words fit guides use, such as straight, tapered or relaxed, say where each edge lands on the body, and choose poses that let the garment hang. Then compare every photo with the real garment.
Fabric words that give the model something to draw
Ask for "premium cotton" and an image model has nothing specific to draw, so you tend to get a smooth, generic cloth. Ask for "2x1 twill with a visible diagonal line" and it has a structure to draw. Use the textile names from your spec sheet, then add what the eye sees at the distance of the shot. The definitions below are from Cotton Incorporated’s textile glossary.
| Say this | What it is | What the camera sees |
|---|---|---|
| Plain weave (poplin, oxford) | The simplest weave; oxford weaves two warp yarns as one | A flat, even face; oxford shows a small basket texture |
| Twill (denim, chino, gabardine) | A basic weave known by the diagonal lines across its face; denim is usually a 2x1 or 3x1 twill | Diagonal ribs that catch light at an angle |
| Herringbone | A broken twill: several right-hand twills, then several left-hand | A zigzag running in columns |
| Satin or sateen | Long floats and no twill line; sateen is a satin weave in a fiber other than silk | A flat, shiny face that reflects light in broad bands |
| Single jersey | A plain knit whose face and back look different | Fine vertical columns of loops, as on a T-shirt |
| Piqué | A knit made of knitted and tucked stitches | A small raised honeycomb, as on a polo shirt |
| Corduroy | A cut pile woven in vertical ribs called wales | Raised ribs with soft shadows between them |
| Brushed or napped | Finishes that raise fibers on the surface | A soft haze over the weave |
| Garment-dyed or stone-washed | Dyed after sewing, or washed for a worn look | Uneven color at seams, edges and folds |
| Weight (ounces per square yard, or GSM) | Ounces per square yard is the usual US weight for denim and other fabrics; GSM is grams per square meter | Heavier cloth makes fewer, deeper folds |
Add three words for behavior. Drape is how fabric falls under its own weight. Hand, in Cotton Incorporated’s glossary, is how it feels: soft, stiff, raspy. Luster is its gloss or sheen. A model cannot feel hand, so translate it into what shows: "stiff raw denim that holds sharp creases" or "fluid viscose that falls in narrow folds".
Light that shows texture
Conservators photograph surface texture with raking light, which the National Gallery in London defines as light from one side only, at an oblique angle to the surface. Fibers facing the light brighten and those facing away drop into small shadows, which is how a weave becomes visible. Flat light from the camera position fills those shadows and hides the weave.
Write the light as something falling on the fabric, with a side and an angle: "hard raking daylight enters at a 45-degree angle across the chest." Keep store photos in soft, even light so the color reads true, and save raking light for detail shots, where texture matters more than evenness. More light words are in lighting terms for AI prompts.
A fabric close-up prompt we kept
This close-up of a striped henley was kept on one of our 2026 apparel jobs, made on Nano Banana 2. Its reference image showed the model wearing the garment.
A tight chest crop of the model shown in the reference image wearing the exact striped henley pullover from the reference, two wood-grain henley buttons visible at the placket, drawstrings resting asymmetrically across the chest, subtle woven patch on the left breast, subtle natural breathing shaping the drape. Background is a softly out-of-focus Sea Foam White #F2F5F8 seamless cyclorama falling completely away to push all attention onto foreground fiber. Hard raking natural daylight enters at a 45-degree angle across the chest, carving the herringbone weave and revealing the muted dusty mauve and Faded Sky Blue #B0C4DE threads inside the stripes. Shot on a 100mm macro lens at f/4, hyper-crisp focus riding the button and the adjacent thread structure, 1:1 square crop centered on the placket. Digital medium-format color profile graded toward Kodak Portra 400, clean near-zero grain, balanced contrast preserving honest shadow detail inside the fabric folds, natural saturation emphasizing the washed, lived-in heavyweight cotton texture.
It names the weave (herringbone), the trims (two wood-grain buttons, drawstrings, a woven patch), the light as an act (raking daylight at 45 degrees), the lens (a 100mm macro, built for close focusing, at f/4) and where focus sits (the button and the thread beside it). The last sentence asks the color grade to keep "honest shadow detail inside the fabric folds", so the texture survives in the shadows. For lens words, see camera and lens terms for AI prompts.
Fit words, and where each edge lands
Borrow fit words from fit guides, because shoppers already know them. Levi’s defines its denim fits like this:
| Fit word | Levi’s definition | Add to the prompt |
|---|---|---|
| Straight | Same width at the knee and the leg opening | Where the hem lands on the shoe |
| Tapered | The leg opening narrows from knee to ankle | How narrow the hem is |
| Slim or skinny | A closer cut from waist to ankle | Whether the fabric touches the thigh and calf |
| Relaxed | A straight fit with more room throughout | Where the extra room shows: seat, thigh |
| Loose or baggy | Oversized, with maximum room | Where the fabric stacks at the hem |
| Bootcut | Narrower at the knee, wider at the ankle to fit over shoes | How much of the shoe it covers |
Then name the landmarks, because models guess length badly. Say where trousers end: above the ankle, at the ankle, or resting on the shoe with a slight fold (tailors call it the break). Say where a top ends (at the belt, mid-hip, below the seat), where the shoulder seam sits (on the shoulder point or dropped down the arm) and where sleeves end (wrist bone, knuckle). Cropped only means shorter than usual, so say where.
Shoppers read fit closely. In Baymard Institute’s 2026 survey of 1,922 US online shoppers, size accuracy and fit details were the information people looked for most in apparel reviews, at 48 percent.
Poses that show fit instead of hiding it
| Pose | Shows | Hides |
|---|---|---|
| Standing upright, weight on one leg, arms relaxed at the sides | True length and silhouette, and how trousers drape | Little. This is the store pose |
| Mid-step walk | How the fabric moves and where it pulls | Exact hem length |
| Hands in pockets | A relaxed, worn-in look | Pocket shape and the waist, where fabric bunches |
| Arms raised or crossed | Stretch in the back and sleeves | The garment’s resting shape |
| Seated | How the rise and seat behave | Length. Amazon does not allow it in adult clothing main images |
Our kept trouser store photos used the first pose, written as "standing composed and upright with a subtle weight shift resting smoothly on the right leg, arms relaxed at the sides." Keep walking and seated poses for secondary and editorial photos.
Check fabric and fit against the real garment
- The photo and the garment side by side under daylight-balanced light, never the photo against your memory
- Weave direction and scale match: twill lines run the same way, herringbone columns are the same width
- Knit reads as knit and woven reads as woven
- Sheen matches: matte stays matte, and satin keeps its bands of light
- Folds fit the weight: heavy fabric makes a few deep folds, light fabric many small ones
- Hem, cuff and waist land where they would on a person of the listed size
- No fabric clinging or stretching where the garment has no stretch
- Color matches on a calibrated screen (Amazon requires the image color to match the product for sale)
- No texture invented where the fabric is plain
Size-specific fit has its own risks, covered in how to show clothes on different body sizes. For everything else, use the AI image QA checklist.
Questions people also ask
- Which image model renders fabric best?
- It changes from month to month, so test on your own garment. Our kept trouser store photos, a houndstooth wool in soft studio light, came from GPT Image 2, and the kept knit close-up above came from Nano Banana 2, but each job changed the model and the shot at the same time. See which AI image model is best for product photos.
- Should fabric weight go in the product copy too?
- Yes. A photo cannot show weight reliably. Put the weight (GSM or ounces per square yard), fiber content and stretch in the description, and let the close-up show the texture.
- How do I stop AI adding wrinkles?
- Say which creasing is allowed, for example "light natural creasing at the elbows and behind the knees, pressed everywhere else." Remove creases a pressed store sample would not have, and keep one garment spec so every photo in the set shows the same level of pressing.
Where Overs fits
In Overs you choose the image model for the final photos. ChatGPT Image 2 (about $0.21 a photo at top quality) is often better at fabric and bright studio light, and Nano Banana Pro (about $0.134) is best at fine detail and matching references. On Pro and Team plans, a reviewer checks each photo against the references before you see it.
Free for 40 photos a month. The AI that makes the photos is billed separately, on your own key, with no markup from Overs.
