Put a flat logo design onto a realistic apparel mockup

Places a flat, uploaded logo or design onto a specific garment with real fabric texture, print-method finish, and body drape — the step between a finished design file and a mockup that actually looks worn or laid out for sale.

The prompt

Ready to copy — highlighted parts are example details you can swap.

You are creating a realistic apparel mockup from a flat design file. The uploaded logo or design must be applied to the garment as if it were actually printed or embroidered there — not pasted flat on top like a sticker.

DESIGN
a two-color circular badge logo, cream and forest green, roughly 4 inches in diameter, uploaded as a flat file.

GARMENT
a heavyweight cotton crewneck sweatshirt in heather oatmeal.

MOCKUP FORMAT
worn by a model, three-quarter angle, cropped from mid-thigh up. If this is a worn mockup, the model's pose, body type, and any visible skin or hair are not the subject of this image and should look natural and unremarkable — the garment and design are what this mockup needs to sell.

PLACEMENT AND SCALE
centered chest placement, sized to sit comfortably within the upper chest area without approaching the collar or shoulder seams. Render the design at a size and position that matches how a real print or embroidery shop would actually place it — centered chest placement, a left-chest placement, or a full-back placement each have different conventional proportions relative to the garment, and the design shouldn't look randomly sized or positioned without regard to that convention unless a specific unconventional placement was requested.

FABRIC AND PRINT PHYSICS
screen-printed finish — slightly raised, matte, not glossy. The design needs to follow the actual garment surface: if the garment has folds, a curved seam, or is stretched across a body's chest or shoulder, the design should bend and compress with that same surface rather than floating flat and undistorted above it as if it were a separate overlay layer. Match the print method's real texture too — a screen-print sits slightly raised with a slightly matte finish, an embroidered logo has visible thread texture and a subtle raised outline, a heat-transfer vinyl print has a distinct slightly glossy, slightly rubbery sheen — pick the one that matches what was actually requested and render its texture accordingly, not a flat, textureless color fill.

SETTING
a plain, softly lit studio background in warm light grey, nothing else in frame.

LIGHTING
Light the garment the way a real product-photography setup would, letting fabric folds and the design's actual surface texture catch light and shadow naturally — this is what makes a mockup look like a photograph of a real printed garment instead of a flat digital rendering with an image stamped onto it.

OUTPUT
One mockup image with the design applied convincingly to the garment's actual surface, ready to use as a listing image or a client-approval preview before an actual print run is ordered.

Optional — swap in your own details for the highlighted parts above.

Why this works

The instruction to make the design bend and compress with the garment's actual surface — rather than float above it undistorted — targets the single most common tell of a low-effort apparel mockup: a design that reads as a flat rectangle pasted over a photo, ignoring the fact that fabric across a chest or shoulder is a curved, folding surface, which a viewer's eye registers as fake almost instantly even if they can't articulate exactly why the mockup looks off. Second, naming the actual print method — screen-print, embroidery, heat-transfer vinyl — and describing each one's distinct real-world surface texture matters because these three methods genuinely look different in a way that affects a buyer's or client's expectations: a mockup that renders every design as a flat, textureless color fill regardless of what production method was actually planned sets an expectation the eventual physical product won't match, which is the same delivered-versus-photographed mismatch problem that shows up in food photography and product photography alike, just with a different failure mode specific to how ink or thread actually sits on fabric. Third, keeping placement and scale tied to real print-shop convention rather than an arbitrary size and position is what makes the mockup usable for its actual business purpose — a client or customer evaluating a mockup is implicitly comparing it against every other centered-chest or left-chest design they've seen, and a design placed at a genuinely unconventional size or position without that being the deliberate ask reads as unprofessional or amateur regardless of how well-rendered the fabric physics otherwise are, which is why the brief treats placement convention as its own explicit constraint rather than leaving it to whatever position looks visually balanced in isolation.
