Standing out from the crowd! Lena Dunham makes an impression in vibrant pink and orange dress as she attends star-studded charity cocktail party

She completed filming for the fifth season of HBO hit Girls last week, but while some actresses would spend this time putting their feet up, Lena Dunham has been attending charity events.

The actress turned up at the Pink Sunset Cocktail party, which was held in Bridgehampton, New York, to benefit the Breast Cancer Research Foundation.

Lena, 29, looked striking in a billowing fuschia and orange sleeveless dress.

She teamed the colourful frock with silk pink heels with unusual pom-pom detailing as she posed next to a surf board at the event.

Thanks to the tiny frock's short sleeves, the tattoo on her right arm was on full show, and with the short, billowing hemline, she also flashed her shapely legs.

The annual fund-raiser - in which Gwyneth Paltrow also attended - is a two-part event, culminating in the lavish soiree.

Earlier in the day, Lena took part in a paddle board race held at the Hamptons to benefit the Breast Cancer Research Foundation.

Go for summer brights with Lena's dress by Lisa Perry

What has Lena Dunham even dun, we hear you ask? Oh, just created a hit TV series, written a best-selling book, cultivated a seriously chic pixie cut...and amidst all that, she's also got one of the quirkiest wardrobes in the business and we love it!

From H&M to Alexa Chung for AG she likes to mix up her high street and designer, and did so again with this ensemble. She paired super-cute ASOS pom pom pumps with this killer colorblock dress by New York-based designer Lisa Perry.

Known for the vibrant, colorful dresses, the label has been worn by everyone from Kendall and Kylie Jenner to Katy Perry and Iggy Azalea.

We love Lena's pick here for that delicious fuchsia/coral colorway, and chevron stripe detail. Styled with statement pumps or tan sandals, this dress, which you can buy with a click to the right, will be the perfect summer frock.

She posted a picture of her at sea with the funny caption: 'It's hard to tell from this blurry shot, but this is an image of Laird Hamilton coming to save me.' 

She continued: 'He is literally King Triton and as I struggled to complete BCRF's Paddle for Pink (an amazing event to support breast cancer research) he appeared as if from the ocean's depths and guided me to the finish line.'

Lena, who is dating Jack Michael Antonoff, added: 'I kept screaming "will I make it?!" like we were in a disaster movie. He said "yes, Lena, we will." Ladies, there are still a few heroes we can count on... #ThankYouLaird #paddleforpink #3miles.'
