Lena Dunham, Portia de Rossi and Zosia Mamet should think about hiring a new stylist after their abysmal efforts on the red carpet at the 64th Emmy Awards.

Girls creator Lena Dunham, 26, tried her hand at femininity to soften her tomboy pixie cut, but ended up in a lace Prada dress that made her look frumpy – and a lot larger than she actually is.

Unfazed by her fashion faux pas, and her failure to win one of the four categories she was nominated for on Sunday, Lena Dunham chirpily tweeted her way throughout the evening from the Nokia Theatre in LA.

Praising the leading man of the night, Lena Dunham wrote: “Didn’t @jimmykimmel crush it tonight? The perfect old fashioned host swagger, generous yet saucy. A pleasure to behold!”

Similarly, Zosia Mamet didn’t manage to execute a feminine flair on her Bihbu Mahopatra creation.

Zosia Mamet, 24, who plays Shoshanna Shapiro in Dunham’s HBO show Girls, swept her hair from her face in a gelled down side-parting, while looking a little uncomfortable in monochrome gown.

And while Portia de Rossi usually excels with her all-American girl look, she opted for something more masculine, posing with wife Ellen DeGeneres in an unusual Maison Valentino jumpsuit.

Portia de Rossi’s look divided fans on Twitter, with many complimenting the lace all-in-one and others ridiculing it.

One user of the social networking site wrote: “My god. WTF convinced Portia de Rossi that an old tea towel was appropriate garb for the #Emmys,” while another described her as “lovely in lace”.

Game of Thrones star Lena Headey chose a bewitching Giorgio Armani dress – and Penny Preville jewels – which had criss-cross spaghetti straps and a sheer bodice to show off her back tattoos.

The gown was complete with theatrical sweeping arms that reached the red carpet, and were something akin to Addams Family martriarch Morticia.

But where Lena Headey failed to inject any color, Julianne Moore stepped in – bravely wearing all yellow.

Credit where it’s due, Julianne Moore, 51, easily defied her half century, but the color block Dior Couture gown was somewhat tent-like as it covered her from her neck to her toes.

Ashley Judd turned a pink dream into a nightmare, with her Carolina Herrera custom raspberry silk gown and giant beehive up-do.

The Missing actress saw the funny side of her extravagant hairstyle, tweeting: “My hair is so grand I am sitting on the floor of the car on our way to the #Emmys!”

And despite her dubious candyfloss creation, Ashley Judd certainly knows how to embrace her curves and had the right idea when it came to accessorizing.

She added: “Most important accessory other than our umbrella on 102 F red carpet? Tigers Milk bar. Snacks are crucial! #Emmys.”
