Michelle has often worn dresses designed by Gurung at various important occasions. She was last seen wearing a Gurung dress in April during annual dinner of the White House Correspondents Association.
Gurung was born in Singapore to Nepalese parents and raised in Kathmandu, he began his designing career in New Delhi.
After Melbourne and London, Gurung moved to New York, where he is based now.
