If you're washing your kigurumi onesie for the first time, we recommend using the gentlest setting on your washing machine using cold water and any laundry detergent. This is to keep the fleece fluffy, protect the detailing on the face, and to prevent any dye from bleeding. For subsequent washes the color should be set and you may use warm water if you wish. Fabric softener is optional.
*NEVER use chlorine bleach on your kigurumi onesie. Non-chlorine color-safe bleach is okay.
We prefer to hang our kigurumi onesies to dry, but they take more than a day to dry. If you are feeling lazier (or you just can't wait that long), you can use the gentlest setting (usually air dry/fluff air) on your dryer. What you want is the setting that uses room temperature air as opposed to hot air, which will promote shrinkage. Although not neccessary, dryer sheets will help prevent excess static on your kigurumi onesie (you can also just rub it down with a dryer sheet if you ever find it too staticky). To prevent wrinkles, try to take it out of the dryer as soon as it's done and hang/lay it flat.
*NEVER iron your kigurumi onesie. It won't be pretty.
Over time, you may notice a bit of pilling on your kigurumi onesie. If it starts bothering you, we suggest picking up a fabric shaver (we got ours for under $10 on eBay). They're super easy to use and they get your kigurumi onesie looking like new in no time.
