Celebrities all over the world have had us humming "Wedding March" in our heads all week as they flaunt shimmery white gowns everywhere from Buckingham Palace to New York City.

Kim Kardashian donned a white Lanvin gown at the Amber Lounge Fashion Show - fitting, perhaps, since she debuted her 20.5 carat diamond engagement ring the same day. She wore loose side-swept waves and nude lips to give the look a summery feel.

Michelle Obama wowed at Buckingham Palace in a Tom Ford gown. She topped off the look with white opera gloves, a silver clutch, and teardrop earrings. In keeping with her surroundings, she gave her locks a regal look with a high bun.

Kate Winslet wore a white and black silk faille Narciso Rodriguez dress at the El Museo Del Barrio Gala. Though the black accent on her dress gave the look a more modern feel, she looked classically beautiful with red lips and a dewy complexion.
