love match party. I missed it.

Why did I not know about this?  Does it mean that you turn up with your significant other both already dressed the same? Do you turn up and search for  partner based on the fact that you will both be wearing the same New Balance sneakers? Perhaps you find your love at the party and then the party organisers provide you with same same clothes? How does this happen? I need to get on the party invite list (dude on the poster is a K-POP superstar btw).
