For the second time, Michelle turned up in glamour in a glimmering, cream-coloured, sleeveless gown designed by Khan at Tuesday night's state dinner at the White House in honour of German Chancellor Angela Merkel.
The First Lady made a fashion statement with the dress embellished with silver beads, white sequins and metallic thread in a geometric pattern, Los Angeles Times reported.
The Mumbai born Naeem Khan also designed the gown Michelle Obama wore to the first state dinner she and President Barack Obama hosted for the Indian Prime Minister in 2009.
Thursday's ivory, V-neck column dress was infact reminiscent of that outfit which was instantly labelled, a style success.
The Indian-American fashion designer who runs his own line launched in 2003 is no stranger to celebrities. His designs have been adorned by likes of Beyonce Knowles, Carrie Underwood, Eva Longoria and Brooke Shields.
