Tallulah Willis showcases her toned physique in a black bikini as she celebrates her clothing launch

She’s the daughter of Hollywood stars Bruce Willis and Demi Moore.

And Tallulah Willis is breaking out on her own as she showcased her physique in a black bikini while celebrating the launch of her new clothing brand on Wednesday. 

The actress, 26, looked incredible as she flaunted her toned figure in the Instagram snap while posing with pal Rachael Finley, whom she launched the brand Wyllis with.

Tallulah flashed a broad smile as she launched her hand in the air and held a large black cake, emblazoned with the name of her new fashion line Wyllis.

The sizzling two-piece featured eyelet detailing on the top and high-waisted bottoms, with the ensemble perfectly showing her taut midriff and toned legs.

Tallulah swept her wet-look raven tresses back, while she accessorised with a pair of quirky cat-eye sunglasses.

Meanwhile, another snap saw her wrap her arm around designer pal Rachael, 34, as she stood on a step and highlighted the height difference between the two.

Rachael herself, who owns fashion brands Teenage and Hot Lava, looked stunning in a lime green bikini top and a matching ruched mini skirt.

It was also a double celebration for the duo as they were also celebrating Rachael’s 34th birthday in the sunshine. 

Tallulah shared an image of Rachael’s huge birthday cake on her stories.  

The new clothing brand Wyllis is unique as it features artwork from Tallulah herself in a bid to raise awareness of mental health. 

Speaking about her brand, Tallulah told People: ‘I want it to be an extension of myself. I think that when you do a personally named brand, there is a closer connection because it’s who you are.’

Discussing she wanted it to incorporate the ethos of kindness and compassion, she continued: ‘Because of my own journey and my own struggles with mental health and how closely it resonates with me, and this is a very widespread, universal issue of well-being. I felt that it was something really, really important to touch on and create visibility on [in the line].  

The clothing also includes phone numbers to National Suicide Prevention Hotline and the National Alliance on Mental Illness Helpline on its tags.

Speaking on the importance of this element, she added: ‘It was really important for me because I have personally been actively suicidal and know that feeling very well and know the feeling of being alone in those moments. And this brand really was truly birthed from a deep, dark time in my life where I did feel alone.’
