July 15, 2012 | The Big Party at Eastern Standard

STUFF's pages have frequently featured the work of Opus Affair, a networking group for young professionals with a taste for the fine arts. Now four years old, the growing group is throwing its biggest bash to date: The Big Party. From 1 p.m. to 5 p.m. on Sunday, regulars and newcomers alike will converge at Eastern Standard (528 Commonwealth Avenue, Boston, 617.532.9100), which will be transformed into a 1920s-style garden party à la The Great Gatsby, complete with tasty snacks, inventive cocktails, live music, and games like croquet. Also on the agenda is the unveiling of Opus Affair’s first Audience Choice Award, which will go to an arts organization (like the Boston Ballet’s Young Partners or the Huntington Theatre’s 35 Below program) that excels at reaching young professionals.
