Time Out says
Get decked out in your kinkiest gear—or at least don't show up in an ironic tee and orange Pumas, hipster—for the city's biggest weekly fetish bash. Barbers will be there to help you achieve that sexy buzz-cut look, and bootblacks will keep your kicks glossy as you chug cheap beer. Acceptable attire includes leather, rubber and uniforms. Check the website for more extensive info. And don't fuck it up—the doorman's decision is final.
