At Scout, guests are invited to a lively “Stoplight” party from 8-11 p.m., where attire does the talking. Partygoers are encouraged to wear green if they’re single, red if they’re taken, or yellow if it’s “complicated.” The event is free for all guests, and for those who don’t want to dress the part, corresponding red, yellow or green cups will be provided so everyone can still join in on the fun.
