As the President and First Lady arrived in Rome, Mrs. O dazzled in a yellow sheath dress, accessorized with an oversize green brooch at her shoulder. We love that Mrs. O has mixed two of her signatures - a classic sheath and a statement brooch - while introducing a fresh play on color.
Update #1: Mrs. O wears a Jason Wu canary yellow silk faille custom sheath dress. The pin is a rare 1960s vintage piece in paper mache, purchased at Ikram.
For the afternoon, Mrs. O changed ensembles to visit the Coloseeum with her daughters, wearing a white sundress with an Erickson Beamon turquoise brooch pinned at the neckline. The brooch was first seen in August 2008, as Mrs. O opened the Democratic National Convention.
Update #2: Mrs. O wears a white cotton silk dress by Narciso Rodriguez.
