I remember my first time cosplaying as Len Kagamine xD Wasn't the best (talking about the wig only since it literally died after first use) but wasn't bad either and mom was totally confuse about what I was doing and why I was going such as.
Mom: What are you wearing?
Me: A costume.
Me: For a convention.
Mom: Clown Convention?
Me: At least they entertain me more than this conversation.
Mom: What's that suppose to mean?
Me: (You're boring.)
