Please:
1. take out the accessories (belt, hat, neckwear), don't wash them, but can use a wet towel or hand-wash to clean them gently.
2. overturn the cape, dress, stockings, and gloves, put them into a washing machine bag (to protect the decoration parts on the costume),
3. you can put in the washing machine bag into the washing machine and wash them as normal.
*If you like, and the costume is not that dirty, you can separately wash the costume parts (cape, dress) using a fast mode (like, 15 minutes).
4. you can iron the costume after they dried.
