A vest that Ryan Ross from Panic! At The Disco wore to many concerts, that was a bright red color, with lots of fake roses and a few silver chains on it. However, it was lost in luggage claim one day when they were coming back from a tour. It's also like a mascot to fans of P!ATD/Ryan Ross.
"Man, I'm really bummed that the rosevest is gone."
"Me too, man, me too."
