Best dressed

Samira Wiley, who plays a tomboy character inOrange is the New Black, looked sublime in a shocking pink cape dress. From prison inmate to screen goddess - we adore this transformation.

Naomi Watts did jewelled embellishment perfectly with a simply cut strapless dress falling at the shin, made from two gorgeous fabrics.

Jaimie Alexander gets points for eschewing cute and pretty and going for a daring, futuristic Armani Prive gown with full coverage, and degradé sequins that produced a strobe-light effect.

Claire Danes, who's been on red carpets since she was 15, played it well, pleasing high-fashion critics as well as red carpet fans. Blue and maroon sequins created an interesting pattern on the shimmering Prada gown, and the hefty metal chain straps made for some seriously edgy hardware.

Taylor Schilling, who plays Piper in hit show Orange Is The New Black, looked positively radiant swapping the prison jumpsuit for a lemon-yellow, flowing Stella McCartney gown.

There were those who won by playing it safe: Padma Lakshmi looked stunning in a yellow satin Romona Keveza gown that radiated old Hollywood glamour with a classic train. Jessica Paré, who plays Megan Draper in Mad Men,shone in a stunningly elegant strapless gown.

While most men go for relatively prudent, well-cut tuxedos, eccentric Scottish American actor Alan Cummings blew them out of the water with a grey three-piece suit, "billowing" voluminous pants, a banknote collage tie, maroon pocket square and umbrella. We salute you, sir.

Worst dressed

A shocker in this category was the stunning January Jones in a green Ulyana Sergeenko jumpsuit. These two stylish names should go well together, but they didn't - from the waist brooch to the strange pleated chiffon tail, it was an odd outfit that fell flat.

Emma Myles, from Orange is the New Black, also didn't win any points with a black and painted floral print dress that looked like it'd been dragged out from the back of end of the '80s. Fellow cast member Laura Prepon, who we're usually a huge fan of, disappointed with a gown that could have been worn to the recent China-themed New York Met Gala Ball - and that isn't a compliment. Half-embroidered Imperial empress-y top for just the neck and shoulders, and then a fire- engine red classic fishtail gown - what was she thinking?

The usually on-point Heidi Klum sported a half-and-half, sunshine yellow Versace gown that said both period drama and mermaid movie. A long, barely there netted skirt with a strategically placed leaf shape that barely covered her modesty, and a single, long, swishy, wizard-like sleeve... it was a head scratcher. Still, with her face and body it almost doesn't matter - you could throw a potato sack on this woman and she would still somehow manage to look incredible.

Notably dressed

This is the "wow, well will you just look at that" category. Maisie Williams, who plays the precocious Aria in Game of Thrones, went super feminine with a bubblegum strapless pencil dress and a pair of adorable fluffy white sandals - not the kind of look we're used to seeing on her, but we liked this playful take.

Who is this new Lady Gaga we're seeing a lot more of? She went completely classic chic with a toned-down, one-shoulder, black Brandon Maxwell gown and a swept back blonde bob. It's a far cry from telephone hats and meat dresses, that's for sure.

Some actors are so psychically gifted and ooze such confidence that they make outfits that shouldn't work in theory become red carpet magic. Take Kerry Washington in a sparkly sequinned all-silver Marc Jacobs dress with a thigh slit and '80s shoulders. She's proof that human perfection exists, but we're still not sure she managed to quite pull off this look.

Sofia Vergara put her curves to work with a slick, silver strapless gown (we want to know how this woman manages to look so damn siren-y all the time). And then there's Kathryn Hahn, who wore one of the most experimental dresses of the evening - an interesting, asymmetric construction with a voluminous peplum hem on one side. It's a shame that the fabrics looked stolen from grandma's furniture.
