A saree will get you in anywhere it seems. A recent state dinner at the White House in honor of PM Monmohan Singh and his wife received a pair of unexpected guests. Washington D.C. socialites Tareq and Michaele Salahi thought it would be fun to try and sneak into the state dinner and it worked. Though they had no invitation and weren’t on any guest lists, they managed to make their way through security. Maybe it her chic lahenga saree and his snazzy tux that made security think they were guests? They weren’t even discovered as party crashers until they bragged about getting in to the party online.
