Every cosplayer - no matter how long they've been cosplaying or what skill they're at - has at least one costume that they have been wanting to emulate before they even knew what cosplay was.

I've never met anyone immune to this, and it's super fun seeing friends make their dreams come true and cross that character off their list.
Normally it's something you think about when you first get into cosplay, and then totally forget! Your skills grow and you learn new tricks and suddenly hey - that dream cosplay isn't so intimidating anymore!
