It’s important to clarify that “Opium” is not a person or a specific style of dressing in the traditional sense. “Opium” is commonly associated with the narcotic substance derived from the opium poppy plant. However, if you are referring to a particular character, artist, or subculture that goes by the name “Opium” and has a distinctive fashion style, please provide more information or context, and I would be happy to offer guidance on how to dress like that specific individual or group.
