PJs 'N DJs

For many of us, the days after Christmas are a welcome break from reality where we can lounge around the house in our comfiest clothing, never giving a damn about our appearance. Well, imagine that level of comfort—plus indie and electropop music and a ton of other dancing people in their jammies. That's exactly what you'll find at this Park Slope party. Plus, it's free. No cover and the best dress code ever—now that's how to shake off the post-Christmas blues.
