Poppy Delevingne puts on a VERY busty display in a daring pastel mesh dress as she attends The Hope Gala

Poppy Delevingne wowed in a colorful number as she attended The Hope Gala at the Mandarin Oriental Hyde Park in London on Thursday evening.

The model, 37, caused up a storm in the bold mesh ensemble which was striped with multi-coloured pastel polka dots.

The star, who is sister to Cara Delevingne, made sure to show off her ample cleavage in the dress which featured a plunging neckline down to her navel.

She cinched her waist with a rose gold belt adorned with a gold floral brooch.

The event was hosted by actress Alia Bhatt in support of the Salaam Bombay Foundation works to engage Mumbai’s most vulnerable ‘at-risk’ children through after-school academies and school-based programs.

Poppy looked cheerful as she attended the evening, sweeping her blonde locks back into a sleek, sleek bun.

Her dress fell to the floor and also wrapped around her neck in an elegant scarf.

The evening marked Alia’s first-ever charity event in London, as one of the most successful actors in the industry to have represented India internationally.

Posing next to Poppy, she opted for a beautiful black dress with straps and silver trim.

The actress, 31, accessorized her look with an elaborate silver and blue jeweled necklace that formed the centerpiece of her look.

While Poppy attended the charity event, she was absent from her sister’s Cabaret Gala night at the Kit Kat Club, which took place the same evening.

Cara, who stars as Sally Bowles in the famous West End production, made a chic appearance for the occasion in a stylish brown blazer-style mini dress.

The model showed off her slim physique in the ensemble as she put on a very leggy show in the dress which she paired with a pair of knee-high black socks and heels.

Cara accessorized the look with a black leather belt and bold red lip, while her brunette locks were tied back away from her face in a shaved bun.

In the role of Sally Bowles – made famous by Liza Minnelli in the 1972 film version – Cara follows in the footsteps of Oscar nominee Jessie Buckley who previously played the role.

She appears alongside Olivier award-winning Luke Treadaway, who stars as The Emcee in the iconic play.

Last month it was announced that Cara would be taking on the role, as she said at the time: ‘there are no words to explain her excitement’.

The duo will perform for three months, from March 11 to June 1, 2024.
