How to clean, care for and store your cosplay costume
A well-made costume lasts years if you look after it, and a badly stored one can be ruined in a single weekend. The good news is that cosplay care is mostly about doing the boring things immediately after a convention rather than anything technical.

The day you get home
Do not leave a worn costume crumpled in a bag. Take everything out, hang fabric pieces in a ventilated room, and let sweat and body heat evaporate. Then inspect for damage while you still remember what happened — loose seams, missing gems, scuffed paint, tangled wig fibres. Noting repairs now is far easier than discovering them the night before your next event.
Fabric costumes
- Check the garment tags first, always.
- Hand wash in cold water with a mild detergent. Sports-wash detergent is good at removing convention sweat without damaging fabric.
- If the tag allows machine washing and there are no delicate embellishments, turn the garment inside out, put it in a mesh laundry bag, and use a cold delicate cycle.
- Never put a cosplay garment in a dryer. Heat melts synthetic fibres, shrinks fabric and warps glued details.
- Air dry flat or hanging. Faux leather should hang dry, out of direct sunlight.
Wigs
- 1Detangle from the tips upwards with a wide-tooth comb, never from the roots down. Work slowly.
- 2Wash in cool or lukewarm water with a small amount of mild shampoo. Swish gently — do not scrub or twist, which causes permanent matting.
- 3Rinse thoroughly with cool water, then apply a little conditioner, avoiding the roots and any glued styling, which conditioner can loosen.
- 4Dry on a wig stand or foam head. Do not use a standard blow dryer unless the wig is heat-resistant and you are actively styling it on low.
Armour and props
- Wipe down with a damp microfibre cloth and a drop of mild dish soap, inside and out, then wipe again with clean water.
- Touch up chips with acrylic paint and reseal with a clear coat if needed.
- Inspect elastic, velcro and buckles. Sweat weakens the glue holding straps to armour — reinforce now, not at the next convention.
Storage
| Item | How to store it | Avoid |
|---|---|---|
| Structured garments and dresses | Padded hangers in a breathable garment bag | Clear dry-cleaning bags, which trap moisture and can yellow fabric |
| Knits and heavy items | Folded flat in a clean bin | Hanging, which stretches them out of shape |
| Styled wigs | On a stand or foam head, covered with a hairnet or dust bag | Cramming into a bag, which destroys the styling |
| Armour and props | Flat or supported with tissue, in a cool dry place | Heat, direct sunlight, and stacking, which warp foam and thermoplastics |

Common questions
Can I machine wash a cosplay costume?
Sometimes, but only if the tag allows it and there are no delicate embellishments. Hand washing in cold water is the safe default for almost every cosplay fabric, and it costs you twenty minutes.
How do I stop a styled wig from losing its shape?
Store it on a stand or foam head, not folded in a bag, and cover it with a hairnet or breathable dust bag. Most wig damage comes from storage, not from wearing.
Will armour warp if I store it badly?
Yes. EVA foam and thermoplastics warp under weight or heat — a hot car boot is enough to ruin a pauldron. Store armour flat or supported, in a cool dry place, out of direct sun.
