Taking to her Instagram Story, Klum showed off a video of her working out in a sheer black floor-length gown with a scoop neckline and striped hem. The dress was completely see-through, allowing Klum to showcase her black bra and matching shapewear she wore underneath. She added some rock-star edge to her look by topping her dress with a silver leather biker jacket, featuring black panels and an extra-long belt that she left unfastened.
These past few years, style savants have taken to showing theirs off, whether under see-through fabrics or skipping traditional clothes altogether, instead substituting boudoir options for tops or pants. Fashion's trendsetters, however, took lingerie dressing a step further. Rihanna, for example, matched her cheeky thong to her shoes, and Elsa Hosk turned her striped co-ords into a three-piece set by wearing a bra in the same pattern. Julia Fox, meanwhile, took the beauty route and matched her brassiere to the shade of her lipstick.
