Keep a plus-size character’s shape consistent.

Choose three features that define the character’s outline. For one adult woman, those might be a broad torso, full upper arms, and wide hips. For another, they might be a rounded abdomen, narrower shoulders, and strong calves. These are different briefs even if both characters are described as plus-size.

Use ordinary visual language. A numeric clothing size means different things across garments and markets, and it may not help the model at all. Relative descriptions such as broad shoulders or a waist close in width to the hips are easier for a human reviewer to apply to an image.

Keep the face, age, and hairstyle in a separate identity sentence. This makes it easier to see whether a failed result concerns body shape or the person’s identity. Avoid adding contradictory terms copied from a prompt collection just because they appeared in a successful image elsewhere.

Proposed prompt, not a measured result: “Original fictional adult woman in her thirties, plus-size build, broad torso, full upper arms, wide hips, short curly brown hair, loose linen shirt, straight-leg work trousers, sturdy boots, standing at ease, full-body anime concept illustration, simple pale background.”

The occupation can enter the second pass through a gardening apron or notebook. Do not start by filling the image with foliage that hides the silhouette. First decide whether the model produced the intended character, then add objects and scenery that support the role.

Keep accepted and rejected images together during selection. A prettier face can distract from a body that no longer follows the brief. If no result preserves the three shape anchors, reconsider the selected model before spending the rest of the budget on scenery.

Specify the garment type and cut: an open overshirt, straight-leg trousers, a structured coat, or a loose dress. Those choices affect the outline differently. “Stylish clothing” gives the model much less direction and can lead to an outfit that conceals the body choices you wanted to review.

Look for seams that connect, sleeves that leave room for arms, and folds that respond to posture. A waistband should not disappear on one side without a visual explanation. Logos, embroidery, and repeated fasteners often need a separate editing pass, regardless of the character’s body type.

A garment can fit closely or loosely by design. The review question is whether the image supports that choice consistently. Do not treat tight clothing as an automatic requirement for showing body shape; an open jacket and clear posture can communicate it without sexualized framing.

A seated pose changes how the outline appears. Clothing folds, torso angle, and limb overlap all shift. That does not mean the character should acquire a different frame. Compare shoulder width, upper arms, face, and leg proportions rather than expecting the standing silhouette to remain identical.

Start with a simple chair and visible feet. Check where the body meets the seat and whether the chair’s geometry is coherent. If a desk hides the lower half, you lose information needed to judge posture. Add complex furniture after the pose works.

A pose reference may guide structure but can also pull the result toward the source image’s proportions. Where the model supports references, review that tradeoff rather than assuming a reference fixes everything. Keep the written body brief visible while comparing the output.

If the character keeps becoming slimmer, inspect the whole prompt for competing style and body cues. A phrase asking for an exaggerated hourglass shape can undermine a brief with a broad waist. Change one conflicting phrase, then compare the next result with the same acceptance notes.

Negative prompts are model-dependent. Do not expect them to enforce exact proportions, and long lists can introduce their own problems. Start by making the positive description coherent. Use only exclusions that address an observed failure and are supported by the selected workflow.

Image-to-image can help explore changes from an accepted source where available, but stronger changes may alter the shape you wanted to preserve. Keep a copy of the original and compare visible changes. Do not claim a setting is optimal without testing it on the model and image in use.

Let the character’s action carry the scene. The botanist can explain a plant, hurry to a meeting, or repair a greenhouse. Body shape can remain visible without becoming the subject of every caption. Avoid using food, clumsiness, or insecurity as automatic personality cues.

For a group illustration, give each character an independent silhouette and role. Repeating one face with different body sizes produces a weaker cast than choosing distinct posture, clothing, and interests. Compare the cast as a whole before refining decorative details.

Use fictional adult designs and sources you have permission to upload. Do not alter a real person’s body for ridicule or present a generated body transformation as evidence of what happened to them. A character-design brief does not need a real person’s private photographs.

Pair the accepted image with the three shape anchors, a short clothing description, and notes about any defects. If a hand is wrong but the silhouette is right, say so. The next artist should not have to guess which parts of an AI concept are intentional.

Ask for a human editing pass when exact proportions must survive across a cast sheet, comic, or animation. Several attractive generations are not a coherent production set. Approve a final reference and use that as the source for later work.

Keep the source image, exported copies, and permissions in a project folder outside the browser gallery. Name the version you approved. That small record makes it easier to return to the intended character after a week of experiments.
