She is often known for raising eyebrows.

So fans of Lindsay Lohan were surely not disappointed when she attended a formal function in a sheer dress on Sunday – which completely showed off her underwear.

The actress was a special guest at the inaugural Visa London ePrix dinner at the Natural History Museum, where she certainly gave onlookers an eyeful.

The actress stepped out in the black number wearing just an additional pair of shoes, which certainly kept attention focused on the daring dress.

Featuring a combination of both lace and sheer panels, it showed off far more than it covered – despite being a floor-length gown.

And yet, somehow, it still managed to look classy in its conception and execution.

Keeping her make-up sheer for the occasion, she sported a slightly sunkissed appearance, which was anchored by her long – and increasingly blonde – hair.

Accessorising with a dainty gold necklace and a matching bracelet, the starlet was on strong sartorial form and appeared confident and composed.

There, she led a host of other celebs including Jodie Kidd and Sarah Ferguson.

Dressing to impress in a sleeveless jumpsuit, the former model looked statuesque in her choice of attire.

Wearing her hair back for extra effect, she added some silver jewellery and a pair of open=-toes sandals to the mix.

Considering she’s tipped to feature in the new line-up of Top Gear, the star was certainly an appropriate guest at the event.
