My first thought was there’s a lot of black at this premiere.

But considering 2 funerals took place in LA yesterday, I think it’s fitting that some of the stars wore black as a mark of respect.

Rumer was a shoe in for Best Dressed this week with her Zac Posen dress, but her Stella McCartney ensemble has trumped that look.

I have been rooting for Rumer for a very long while, and for the second time she gives me red carpet head-to-toe perfection.

The lace jacket hints at nudity without being tacky, whilst the black pants completes the sleek silhouette.

Her deep brunette hair is swept to the side, with jewels kept to a minimum.

If you are feeling a touch of de ja vu with this look, it’s because Stella McCartney wore the jumpsuit version of this lace look to the 2009 Costume Institute Gala.

For once Rumer isn’t upstage by her mother…

…who btw looked stunning wearing a black Oscar de la Renta Resort 2010 dress with black satin Brian Atwood pumps.

Demi Moore’s dress had a large rosette detail on the neckline, from which large ruffles cascade down the front of her dress.

So ladylike, so chic, so Demi, so glad she wore the runway belt. I’m not sure the dress would’ve worked without it.

Audrina Patridge has walked the red carpet a few times without her favourite Alexander McQueen bow clutch, but it was back last night.

The actress wore a black strapless textured See by Chloe dress, with a tie to the waist and a tulip skirt, with Alexander McQueen strappy sandals.

I know blondes are meant to have more fun, but I hope Audrina returns to the darker locks soon.  The blonde was cute a first, but it’s starting to lose it’s original spark.

Jamie Chung looked sassy wearing a rubbery LBD by Giorgio Armani paired with Brian Atwood heels.

The dress is interesting with those sharp details cascading from the shoulder, but what I love here is her flawless make-up.

Margo Harshman opted for a creamy Gustavo Cadile Fall 2009 strapless gown.

I love the ruched bodice and the gold band on the empire-waist, she really looks so elegant in this stunning gown.

A gold clutch and her hair swept up completes this beautiful look.

I didn’t expect to see this ivory Miu Miu Spring 2008 mini dress on the red carpet again, but Jasmine Dustin gave it another outing.

It’s still such a stunning dress, but it really deserved better shoes.

Whilst everyone opted for something youthful, I think the black satin gown Briana Evigan wore was a bit of a safe option.

Caroline D’Amore wore a sexy Dolce & Gabbana trademark strapless bustier dress with a eyelet skirt.

She paired her dress with silver strappy Jimmy Choo’s and a matching clutch.

TV personality Casey Reinhardt wore a Alice + Olivia taupe dress with leg lengthening nude heels.

Sorority Row hits theaters across the US next Friday, September 11, but in the UK it comes out on September 9.
