Gwen Stefani attended the Cannes premiere of The Tree of Life this weekend wearing a long-sleeved, sequined Stella McCartney jumpsuit with a skinny black belt. It's the same piece Iman wore to this year's Met Ball two weeks back, except in black, not gold. Though her shoes were hidden under the long pant-legs, she carried a small clutch, chose a bright pink lipstick, and curled her hair out.

Are the jumpsuit's proportions really working for Gwen? And is she giving Iman a run for the high-glam fashion title?
