Another month, another iteration of State Theatre's two-night party, billed as D.C.'s "biggest '80s Retro Dance Party," where guilty-pleasure hits from now nearly three decades ago are given the full tribute. Many in the crowd come dressed to the nine: shellacked big hair, lacy ankle socks, stirrup pants, parachute pants or anything else big in the '80s. Friday, July 30, and Saturday, July 31, at 9 p.m. The State Theatre, 220 N. Washington St., Falls Church. Tickets are $17. Call 703-237-0300 or visit thestatetheatre.com.
