Heidi Klum was flashing the flesh in California last night, when she swept into the Annual Los Angeles Antiques Show in this daring Michael Kors jumpsuit.
While from the front, the high neckline and wide-leg trouser sillhouette may have looked relatively demure - but once she spun around, the trick-of-the-eye design gave the impression that she'd forgone a top entirely, with nothing but a scarf falling down her back.
37-year-old showed off the revealing backless number to full effect, by scraping her hair back into a high swinging ponytail, and working some well rehearsed poses for the cameras.
