Where colour can come from
Colour transfer may involve the fabric face, its backing, seams, thread, trims or another accessory. Dark and saturated pieces deserve particular attention, but colour alone cannot tell you whether a material is compatible with a specific body.
IRIS selects materials with reduced colour transfer in mind. Differences in body formulation, contact time, pressure and the condition of a garment still matter. Do not assume that a national origin or a premium price guarantees zero transfer.
Before a new outfit meets a favourite body
- Confirm compatibilityCheck the exact body model and material. Silicone and TPE are not interchangeable, and a seamless description does not identify the polymer.
- Test cautiouslyFollow the body and costume makers’ compatibility instructions. A hidden-area test can reveal a problem but cannot guarantee that longer contact will be safe.
- Reduce prolonged pressureAvoid excessively tight fits and extended unattended wear. During initial use, inspect contact areas frequently. Remove the outfit when you finish photographing.
- Choose a tested barrier if appropriateA compatible undyed liner or temporary barrier may reduce direct contact. It must fit without bunching and be checked for its own tendency to transfer or stick. Powder alone is not a dye barrier.
After each scene
Remove the outfit, inspect both surfaces and store them separately. If you see a new mark, stop using that pairing until you understand the cause. Photograph the change and note the body model, outfit, duration and conditions to make advice from the maker more useful.

Build a repeatable care routine
- Inspect and record: identify the body material and clothing backing; record time, temperature and humidity. The source’s 24-hour test can itself stain a body, so prefer approved spare material and stop at any change.
- Reduce contact: use compatible pale innerwear or lining. Film is temporary; avoid tight wrapping and trapped moisture, then remove it. Powder alone does not block dye.
- Undress and inspect: the source’s 1-3 hour shoot and 6-8 hour display intervals are inspection reminders, not safe limits. Store dark clothes separately and check weekly for shadows, colour changes and tackiness.
The Japanese original is unchanged. It mixes TPE and silicone terminology and describes a 10% BPO treatment lasting 24-72 hours. This differs from the separate 12-hour IRIS example; neither is a validated procedure for every body. Use oils, detergents, chemicals and powders only as approved for the specific body and clothing.
