She's been one of the main players in bringing the Lady Garden charity to the forefront of public awareness.

And Suki Waterhouse continued to campaign for the cancer charity on Tuesday night, as she turned out for the  Lady Garden Gala in London.

Kooky Suki wore a completely sheer skirt, with her bright pink knickers on show, being deliberately brazen in aid of the Silent No More Gynaecological Cancer Fund.

Suki showed off her lithe model figure with a chunky white belt marrying together a tulle top and skirt.

Going braless beneath, Suki picked out a low-cut top that plunged all the way down to her waistbelt and was accessorised with gold necklaces.

Feeling kooky, Suki added a designer shopping bag as an accessory to carry her belongings for the evening.

But the main event was her see-through skirt that saw her flashing her underwear, as was as her lithe legs. 

The glamorous bash, hosted alongside Cancer Research UK at Claridge's hotel, was star-studded affair, with attendance from Clara Paget and Mika Simmons, along with campaign co-founder Chloe Delevingne. 

The campaign was co-founded by model Cara Delevingne's older sister Chloe, and Cara along with their middle sister Poppy have played a huge part in supporting the campaign publicly.

Chloe spearheaded the campaign when  pre-cancerous cells were found in her cervix.

In September, the model spoke to Vanity Fair about her hopes that women could be more open about their vaginas.

She said: 'I remember at school talking with some friends, and saying we had 'two holes', and we got in trouble with the teachers. 

'So it was kind of ingrained in us that it was a private thing. And, in the classic British way of 'keep calm and carry on,' we never discussed things like Pap smears and other important issues that need to be discussed.'

Suki concluded: 'Half the population has a vagina and a period and it's still something that seems to be 'embarrassing' to talk about.'

Other guests included former Spice Girl Mel C who dazzled guests with her vocal talents on stage. Her appearance came amid recent reports the 90s girlband are finally reforming, having managed to persuade Victoria Beckham to get on board with a comeback. 

She, however, hadn't been the only one to previously rule out a reunion, as Mel C had insisted that such a comeback would 'fail'.

Appearing on The Night Show in March earlier this year, Mel addressed rumours the Spice Girls will reunite as a four, without Victoria, and said: 'It's not really doing the band justice to go out as a four piece.'

Explaining further, she revealed: 'Whoever's missing, it doesn't matter. I think for me Spice girls is like a jigsaw puzzle.

'It's different to other bands. Look at Take That - they're going out as a three piece and they're brilliant. I love the boys!

'But with the Spice Girls, everything about us was the individuality and what that created together,' she continued. 

When it comes to their 'individuality', each member of the group, which was created in 1994, went by a nickname - with Mel being known as Sporty Spice.
