Little Sins is a Dutch dance and lounge concept that describes itself as answering the wish to go out differently. It runs private parties for between 200 and 400 couples at unusual locations — its own examples are castles, caves, churches and boats — built around themed, sensational dress codes and a mix of music and lights.

The organiser is explicit about who its parties are for: couples only, with an age limit of 21 and over for all parties. It describes guests as people who want to dance and party, who look for excitement and adventure, and who want to experience luxury and sensuality — people who like to feel the pleasure of seduction and to find excitement with their own partner and with others in what it calls a secure sexy environment.

The location is never published. The organiser keeps it secret as a matter of policy and sends it only to valid ticket holders, by email to the address the tickets were bought with, twenty-four hours before the party starts. Tickets for all its parties are sold through its own Paylogic ticket shop.
