For all the DC metro types....
The baby branch of Neiman Marcus, Cusp, is having a designer jeans sale. Buy one, get the second half off.
Now a designer jeans sale is about as rare as spotting Trent Lott with bedhead hair, so I advise you drop everything, call in sick (just say you ate at the Subway on 1st St. SE or at a Taco Bell on the campaign trail) and hightail it over to Tyson's Corner.
