>>12649917The thing is that cosplay is never for keeps. Some costumes end up getting sold at a certain point.
That said, it's improbable that you will soak a Misty costume with your manjuice because the person that made/wore the costume is likely thinking about the next person that's going to be wearing it.
The last thought on her mind is going to be selling a 16 year old girl her used Misty costume that was once basting in your semen.
In short, don't come to expect ever achieving this even if your girlfriend can, will or even PERFECTLY cosplays as Misty.
