Arun Gandhi — the grandson of Mahatma Gandhi — will make his modeling debut tonight at the annual From Scotland With Love at Stage 48 in Manhattan. Arun, an activist and lecturer on nonviolence, will be modeling the World Peace tartan kilt designed by Scotsman Victor Spence, who also works closely with the Dalai Lama. Arun will join a number of notables — including “Gossip Girl” actress Kelly Rutherford, CBS Channel 2 anchor Chris Wragge, former Olympic ice skater Michelle Kwan and New York Giant Steve Weatherford — in a celebrity-fashion show at the event to raise funds for the nonprofit Wounded Warrior Project.
