If you've been looking for an excuse to dust off that thrift-store tux or the sequined dress you impulse-bought at Goodwill, your moment has arrived.

Vintage Prom is popping up in San Francisco next weekend — a free, all-ages, pet-friendly market combining local makers, vintage vendors, a live DJ, and walk-in tattoos from Mirage Tattoo running all day long. Prom attire is strongly encouraged, drinks will be flowing, and entry won't cost you a dime.

The format is smart. Free entry lowers the barrier, the DJ and prom theme give people a reason to actually show up and stay, and the tattoo walk-ins are a clever anchor that keeps foot traffic flowing to vendors all day.

Whether you're hunting for vintage finds, supporting a local maker, or just want to slow-dance with your dog in a rented cummerbund, Vintage Prom is the kind of low-cost, high-fun weekend plan this city could use a lot more of. Details on the exact venue and time should be surfacing soon — keep your eyes peeled and your corsage ready.
