You’re sort of the Spiderman of trendsetters. Agile, brave, capable of scaling great heights. But with great power comes great responsibility — not to mention annoyance. Specifically, the irritation of watching lesser mortals rip off your style. How to make sure you’re always one Spidey-step ahead? Check out Hysteria’s secret stash. Tucked away on the second floor of the Alexandria boutique you’ll find exclusive previews from designers like Lela Rose, Chaiken, and Diane von Furstenberg. There are even a few hidden gems (otherwise known as back stock) at 70 to 80 percent off the original price. One more discovery you’re sure to lead the way on. Just be warned: Others are sure to follow. But they’ll be climbing the walls to figure out where you’ll be next. Hysteria, 125 South Fairfax Street, between Prince and King Streets, Alexandria (703-548-1615). By appointment only.
