The 21st annual Screen Actors Guild Awards took place last night at the Shrine Auditorium in Los Angeles, and the stars were out in force. Although the red carpet looks were all a little safer than at the Golden Globes earlier this month, there were some great choices all the same.

As with any awards show though, not everyone got it right!

Here's our pick of this year's best and worst red carpet looks…

The Best

1. Keira Knightley
After her Golden Globes Victorian-style disaster, Keira Knightley showed that she can still rock maternity style with a stunning vibrant purple number from Erdem. Although the actress joked that her waist has "disappeared" since she became pregnant, we reckon she looks as dainty as ever!

2. Emma Stone
Emma's Dior Haute Couture tuxedo dress may have been a hazard for poor Naomi Watts, but we can't deny that she still looked downright fabulous!

3. Emmy Rossum
This sparkling Giorgio Armani dress was a total win for Emmy… we have some serious red carpet envy right now!

4. Lupita Nyong'o
Although there was a somewhat mixed reaction to Lupita's boldly printed Elie Saab dress, we reckon she rocked it. There's such a lack of prints and patterns on the red carpet so this was a refreshing change.

 

The worst

1. Kelly Macdonald
There's nothing wrong with this dress in theory, but it would be more suitable for a debs than a red carpet event we reckon! Looks like the Boardwalk Empire actress wasn't too bothered about making a big impression…

2. Amanda Peet
Amanda's J. Mendel dress was just a little bland for the red carpet, and that lavender colour seriously washes out her English Rose complexion.

3. Rashida Jones
Beach holiday dress? Yes. Red carpet dress? No.

4. Rosamund Pike
This dress might be Dior but it made poor Rosamund look seriously frumpy. Did it have to be so… bulky?!
