hot off the runway

after boarding air force one in thakoon and deplaning in jason yu, michelle obama has surfaced in london this morning clad in a j. crew cardi (now sold-out) and skirt (going fast). does mobama just pop into her local j. crew to pick up some first lady looks? "hey sales clerk, just need some international summit outfits. does this come in blue?" because I have been to some j. crews, and they were full of disorganized merchandise and uninterested salespeople. does mrs. o have to put up with that in her quest for accessible yet fashionable outfits?
