Say you’re an intern and get there early
Here’s what most young kids don’t know, Fashion Week is the #1 week in NYC where slavery is basically legal. Anyone can intern for anyone for that one week, and there are so many interns, no company can actually keep track of who they all are. So, all you have to do is show up very early wearing all black and claim you’re an intern for one of the companies hosting the event, then just hide out in the bathroom until the party starts. Might be a couple hours, but it's totally worth it.
