At the awards, Michelle wore a white dress with tiny, black, bra-style top part and a flowing skirt featuring a thigh-high split.
She paired the dress with black, over-the-knee, lace-up heeled boots which were open-toed and featured numerous holes.
Helen’s black dress which trailed the floor looked innocent from the hips down, but above was a lingerie-style bodice complete with faux-underwear.
Her bare arms exposed the portrait tattoo she has of Marilyn Monroe on her left forearm which she got in 2012, following in the footsteps of Megan Fox.
The Fashion Awards was presented by jewellery brand Pandora alongside its official partners Don Julio, Getty Images and Royal Salute.
It serves as the main fundraiser for the BFC Foundation which supports the future growth and success of the British fashion industry.
Among the recipients on Monday night were five-time Grammy Award winner Sam Smith who accepted the Cultural Innovator Award.
Famed make-up artist Charlotte Tilbury also scooped up a Special Recognition Award and esteemed designer Valentino a Lifetime Achievement Award.
