All-black suit portrait AI prompt

Black suit, black shirt, black background — and gold as the only colour in the frame. The hard part is not the darkness, it is stopping the whole thing collapsing into one shape. Copy the free ChatGPT & Gemini prompt below and keep your own face.

All-black suit editorial portrait made with an AI prompt — a man with arms crossed in a black jacket over an open black shirt on a pitch-black background, wearing gold-frame tinted sunglasses and a thin gold chain
Made with the prompt below — one light doing all the separation.

Black on black is a lighting problem, not a colour one. A black jacket on a black background has almost no tonal difference to work with. Everything here — the side light, the open collar, the gold — exists to put an edge back in.

None of ChatGPT, Gemini or Nano Banana gives you a transformation-strength, identity-strength or beautify control, so the lock is a sentence rather than a setting: keep my exact face, relight and re-dress me, do not restyle my features. Tools that do put a denoise or strength slider in front of you are fine run low, around 0.20–0.35. The only beautify switch that matters here is the one on the camera or gallery app your reference photo came out of.

Use my uploaded photo as the identity and facial reference. Create a photorealistic luxury fashion editorial portrait of me from the chest up, standing confidently with arms crossed against a completely pitch-black studio background. IDENTITY — THE MOST IMPORTANT PART Preserve my exact facial features, face shape, hairstyle, skin tone, age and overall likeness. Do not change my identity, facial structure, nose, eyes, jawline or hairstyle. Do not make the face look like another person. WARDROBE A perfectly tailored all-black suit jacket over a black dress shirt with the top two or three buttons open, for a sophisticated, powerful, minimalist look. Add a thin elegant gold chain necklace, premium gold-frame dark tinted sunglasses, and a subtle luxury wristwatch. LIGHTING Dramatic cinematic low-key studio lighting from one side and slightly above. It should illuminate the face, cheekbones, jawline, neck and upper body while the opposite side falls naturally into deep shadow. Soft specular highlights on the sunglasses, the gold jewellery, the skin and the suit fabric. Keep the background pure black with strong subject separation — the shoulder on the shadow side must stay readable against the background rather than merging into it. EXPRESSION AND POSE Calm, confident, composed and slightly mysterious, with relaxed lips and natural posture. Arms crossed, shoulders square, chin level. REALISM Maintain realistic skin texture and pores, natural beard or stubble detail if present in the reference photo, natural hair texture and realistic proportions. STYLE High-end men's fashion campaign, luxury magazine editorial, cinematic portrait photography, sophisticated masculine aesthetic, premium studio photography. Ultra-realistic, sharp facial detail, subtle contrast, rich blacks, elegant shadows, shallow depth of field, professional retouching without plastic-looking skin. 85mm portrait lens look at f/2.8, high dynamic range, 8K detail. COMPOSITION Vertical 2:3 portrait. Subject centred and slightly above the middle, head and upper torso fully visible, clean black negative space around the subject. DO NOT INCLUDE No words, captions, logos, borders, watermarks or graphic text. No distorted hands or extra fingers. No asymmetrical sunglasses. No over-smoothed skin, exaggerated muscles, cartoon or anime styling, excessive glow, fake-looking jewellery, or unrealistic facial reconstruction.

About this prompt

The crimson overcoat portrait is lit low-key too, but it gives the frame something to work against: a deep saturated crimson backdrop behind a black wool coat, so there is a tonal break between subject and background before the light does anything. This one has nothing: a black jacket, a black shirt and a black background, which on paper is three versions of the same tone stacked on top of each other.

That is the entire problem to solve, and it is a lighting problem rather than a styling one. Without an edge, the outfit and the backdrop merge and you get a floating head. So the prompt spends most of its words on separation — light from one side and slightly above, catching the shoulder, the lapel edge and the jaw, so there is a readable outline where the suit meets the dark.

Three details carry more weight here than they look. The open collar puts a wedge of skin at the centre of the frame, which is the brightest thing in the picture and where the eye lands first. The gold — chain, sunglass frame, watch — is the only colour anywhere, and metal is the one material that reliably throws a specular highlight in low light. And the crossed arms create horizontal lines across the torso, so the lower half is not one flat black rectangle.

How to use it

  1. Tap Copy prompt above.
  2. Open ChatGPT (image generation), Google Gemini or Nano Banana in image-to-image / reference mode.
  3. Paste the prompt and attach one sharp, evenly lit, front-facing photo of your face — flat light works best here, because the prompt supplies all the drama itself.
  4. Put the identity lock in the prompt — ChatGPT, Gemini and Nano Banana have no strength or beautify dials to set, so type it: keep my exact face, relight and re-dress me, do not restyle my features. If your tool does expose a denoise or strength slider, 0.20–0.35 is a sane starting point.
  5. Generate at 2:3 vertical, 1080 px wide or larger.

The three ways this goes wrong

The suit merges into the background. The commonest failure, and the fix is counter-intuitive: do not brighten the image. Raising exposure lifts the background to grey and you lose the black. Ask instead for a stronger rim light on the shadow-side shoulder — separation comes from a hard edge in one place, not more light everywhere.

The face turns plastic. Smoothing has happened somewhere, and it is almost never in the image tool — there is no beautify switch to turn off in ChatGPT, Gemini or Nano Banana. It is usually the phone camera or gallery app that produced your reference photo, which polished the skin before the model ever saw it. Upload an unretouched original, and say the texture line twice: AI image tools have a well-known habit of retouching on top of whatever you request.

The sunglasses come out crooked or mismatched. Eyewear is one of the things image models handle worst, because the two lenses have to agree across a face that is being re-rendered. If a frame comes back asymmetric, regenerate rather than trying to describe the fix — and if it keeps happening, drop the sunglasses line entirely. The outfit works without them.

Making it yours

  • Silver instead of gold works, but reads cooler and quieter. Gold is warmer against skin and shows up better in this little light.
  • Swap arms crossed for one hand adjusting a cuff if you want a less closed posture — it also puts the watch where the light can find it.
  • Want it less severe? Change the black shirt to a charcoal or deep grey one. You lose some of the tonal purity and gain an easier picture.
  • The 2:3 vertical is deliberate — it leaves black space above the head that makes the crop feel like a campaign page rather than a snapshot. Do not crop it out afterwards.
  • If your reference photo has stubble or a beard, say so in the prompt. Models tend to shave you clean in formalwear unless told otherwise.

If you want low-key with colour in it, the crimson overcoat portrait uses the same narrow side light and puts a deep crimson backdrop behind you.

Frequently asked questions.

What is the all-black suit AI prompt?
It is a copy-paste AI image prompt for a luxury editorial portrait: a tailored black suit jacket over a black shirt with the top buttons open, arms crossed, on a pitch-black studio background, with a thin gold chain and gold-frame tinted sunglasses as the only colour. It is written around keeping your own facial structure, so the result reads as a photograph of you rather than a generated stranger.
How do I stop the black suit disappearing into the black background?
With separation light, not more exposure. The prompt asks for light from one side and slightly above, which catches the shoulder, the lapel edge and the jaw and leaves a readable outline against the background. If your result has gone flat, the fix is a stronger rim on the shadow-side shoulder, not raising the overall brightness, which only turns the black background grey.
Why does the prompt specify gold jewellery?
Because in an all-black frame the metal is the only thing that can carry a highlight. Gold catches a warm specular glint on the chain, the sunglass frame and the watch, which gives the eye three small anchor points and stops the picture reading as one dark mass. Silver works too but reads cooler and quieter against black.
Do I need to actually own a black suit?
No. The prompt dresses you, so your reference photo can be anything as long as your face is clear and evenly lit. What matters is the face, not the outfit you happen to be wearing when you take the photo.
Why does my face look plastic in the result?
Because skin-smoothing has happened somewhere before the render, and it is almost never in the image tool — ChatGPT, Gemini and Nano Banana expose no beautify switch to turn off. The usual culprit is the phone camera or gallery app your reference photo came out of, which smoothed the skin before the model ever saw it. Upload an unretouched original, and repeat the texture request in the prompt: realistic pores, natural skin texture, no over-smoothing. AI image tools have a well-known habit of adding their own retouching on top of whatever you ask for, so saying it twice is worth the words.
Is this all-black suit prompt free?
Yes, the prompt is free to copy and use. You need an AI image tool such as ChatGPT, Google Gemini or Nano Banana and one clear photo of yourself. There is nothing to buy.
