Sister act: Lily Allen and her bump join Aunt Sarah in the front row for fashion week

Having established their own vintage boutique, Lily Allen and her sister Sarah Owen have officially joined the ranks of the British fashion pack.

So it came as no surprise to see them in the front row at London Fashion Week on Tuesday.

Bundled up against the cold in a warm winter coat that covered her growing baby bump, Lily and her elder sibling made a rare public appearance together to see the latest designs from Issa.

Whether or not they were there to be inspired by the label's spring/summer 2011 collection, the sisters were on fine form at the Somerset House event.

Giggling and laughing together as they watched the show, they were quite clearly enjoying both the fashion and each other's company.

 

Sat next to Sarah, – who co-founded Lucy in Disguise with Lily – and looking super stylish was American model Amber Rose, an old flame of musician Kanye West.

Issa certainly put on a stand out show. The designs, inspired by the Indian subcontinent, brought a real burst of colour to LFW in keeping with the exotic palette favoured by the east.

Models hit the runway in bright and vibrant shades – whether in the shape of beautifully draped maxi dresses or figure-hugging frocks.  

 

And it was clear that designer Daniella Issa Helayel had been keen to translate some of what she had seen on her first visit to Rajasthan at Christmas.

"I was so inspired and enchanted by the colours of India and how elegant the women in their brightly coloured saris looked," she said.

"I was fascinated by how the sari's were draped and looked amazing on every woman I saw. These women looked so beautiful, adorned with such rich vibrant colours and jewels.
