Dressing up can turn a night of simple dancing into an eve of magical decadence. This week, three of the city’s flashiest fetes have special events worthy of breaking out thematic glamour garb (i.e. baseball cappers need not attend). If you’re reading this Thursday, June 25, prance into Tigerheat, the Amega-pop princess party at Avalon, marking its eighth anniversary. What to wear: Britney-esque bellytops and Lady Gaga space-girl looks for gals, next to nothing for boys. 1735 Vine St., Hlywd. www.tigerheat.com. Club Society has built an increasingly bodacious following, with regulars donning all that is dapper and dandy. For its “Girlie Show” event, they’re celebrating “women, both real and not” (yours truly is a guest host). DJs Missy K and JeniLuv spin, and performances by Naada and Detox are sure to be eye-poppingly extravagant. What to wear: Put on the Ritz! Bordello, 901 E. 1st St., dwntwn; Sat., June 27. www.societyproductions.com. Club-hopping might be in order Saturday as the debut of the new monthly from the Mustache Mondays crew at Echoplex is the same night. “So L.A.” electro duo Mynx and Dominican diva Maluca (best known for her Mad Decent collab with Diplo, “El Tigeraso”) perform. What to wear: L.A. designer chic and anything but a (fake) ’stache. 1154 Glendale Blvd., Echo Park. www.mustachemondays.com.
