Anatomy errors

Anatomy errors are failures in generated fashion imagery where a body is rendered wrongly: extra or missing fingers, fused hands, a foot or ankle turned the wrong way, or limbs out of proportion.

Anatomy errors are the failures people outside fashion know best, and hands are the classic case. In fashion they matter twice: they make an image look artificial at a glance, and they often sit right next to the product, on a pocket, a strap or a waistband.

What to look for

  • Hands: extra or missing fingers, fused fingers, a thumb on the wrong side.
  • Feet and ankles: a foot turned the wrong way. Observers pointed out an ankle pointing backwards in a 2025 brand campaign.
  • Limbs and joints: arms that are too long, elbows that bend wrongly, a leg that disappears behind the other.
  • Proportions: a head too small for the body, or shoulders that change width between images.

How to catch it in review

Review hands and feet deliberately, at full size, in every image. They are easy to miss when the reviewer's attention is on the garment.

How to prevent it

  • Choose poses where hands are relaxed and visible, rather than holding objects or tucked into pockets.
  • Keep hands away from the product's key details where possible.
  • Reject and make the image again rather than repairing a hand; repaired hands tend to show at zoom.
