Best and Worst Dressed: Costume Institute Gala

Besides the Oscar's, this is one of fashion's biggest nights out.  Celebrities, musicians and designers mingled at the event yesterday, which was hosted by none other than Oprah Winfrey.

I'm feeling positive today, so here are the ten Best-Dressed stars of the evening.

Anne Hathaway is stunning in this Valentino gown.  The nude colour works on her, because it doesn't wash her out.  She didn't overdo the makeup and the fit is perfect... The dress is a bit reminiscent of Miley Cyrus' Oscar gown, which was too mature for her.  But on Anne, the frock is perfect for this Young Hollywood actress.

A lot of people dislike Blake Lively's Marchesa mini, but I like this style choice.  We're used to seeing Lively in plain coloured minis with little detailing.  She seriously needs to give up the Herve Leger bandage dresses... this mini is daring and different, and it showcases her hot bod.  The only thing I don't like are the Christian Louboutin shoes.  They are gorgeous and ornate, but a strappy, simple Jimmy Choo metallic or snakeskin sandal would have complemented the dress more.

The reigning queen of Vogue is elegant in a Chanel dress and jacket. I love her haircolour too, it's very vibrant.

Ladies in White:

Emma Watson stunned the crowd in this custom made Burberry gown.  The asymetrical neckline is contrasted by the slit in the middle while the ruching and ruffles make the Grecian gown modern and structured.

Taylor Swift is a red carpet maven and this Ralph Lauren dress is no exception.  It's a nod to the 40s, which is my favourite fashion era.  Swift is always elegant and styled to perfection.  I know I will spend hours trying to recreate her undone fingerwave updo.

Ladies in Vera Wang... no brides this time.

Mariska Hargitay is so elegant in this Vera Wang gown.  The rich navy colour is perfect for the red carpet, unlike the usual nautical or office navy seen on other stars.

Maggie Grace is another example of Vera Wang's brilliance as a couture designer.  The lilac gray colour is beautiful, and the fishtail silhouette shows off her petite curves.

Who would have thought Mila Kunis could look like Hollywood royalty?  Again, Vera Wang dazzles us with layers of black and gray tulle that mesh together to create magic.

Naomi Campbell proves to us that she's still a Supermodel in this Dolce and Gabanna dress.  Less is definitely more, you can never go wrong with a body hugging LBD... er LBG (Little Black Gown)

Jenny from the Block herself was the night's best-dressed star.  She is beyond perfection in this Zuhair Murad gown.  The fabric looks light as air, in my favourite neutral (grey), but is contrasted with an intricate overlay of gold embroidery and beading. 

The Worst

I feel like I'm starting to eat my words, comparing Carey Mulligan to Audrey Hepburn.  The actress was ho-hum in this Miu Miu mini with black opaque tights and black shoes.  The opaque tights are too heavy for this time of year, but at least she is keeping her legs one colour to lengthen their stumpy stature.  The dress doesn't help her out much either.  The fabric looks like it was stolen from curtains you'd find at a Bed and Breakfast. The pockets are deep, and make the look childish, you seriously start to wonder if Mulligan ran away from a playground in this look.

It pains me to put Eva Mendes on a worst-dressed list, but this D&G frock is a disaster.  I don't know who decided that clashing two massive and ostentatious floral prints was a fashion do, but this proves it's a don't, because not even her bodacious bod can save this eyesore.

Oprah Winfrey's BFF Gayle left us saying...WTF? I can't even find the designer either... it makes me wonder, was it homemade?

This Louis Vuitton dress looks more appropriate for Ke$ha if she ever was to attend the Oscars.  On Maggie Gyllenhall, however, it makes her look like an old star trying to be cool in a youthful and crazy couture garbage bag dress.

Oh Katy Perry... did you know her cat is named Kitty Purry? Clever, yes.  Unfortunately, Katy wasn't clever when she picked out this CuteCircuit dress.  She looks like Candy Floss.  Yum, but cavity enducing.  The event is called the Costume Institute Gala, but it doesn't permit you to go around in a costume either.

What the fuck is going on at YSL?  This dress looks like its from Bebe.  January Jones doesn't help it by adding black satin gloves and stripper makeup either... this looks like a Halloween costume of a 1920's hooker.

Rachel Zoe might be a stylist to the stars, but I think she should consult one for herself.  The canary-yellow Marc Jacobs gown would work better on someone younger, and not in velour.  Velour belongs on the tracksuits of soccer moms of middle America.  Not at a Gala like this.

Rachel Bilson looks like she went to her grandma's house and stole her vinyl tablecloth and made a Louis Vuitton dress out of it.  The black shoes and black clutch are too matchy matchy as well.  The hemline should be a good 6 inches shorter, since this length is cutting her legs off.

Donnatella Versace... why must you look like a plastic stripper?  Your looks is as plastic as your face, and chest, and butt and lips and it goes on...  I loved your Spring 2010 collection, but I'm really not digging the cheap shiny fabric and red platforms.

And the WORST dressed goes to... Chloe Sevigny in Proenza Schouler!  Sevigny is so often on the best-dressed lists, she must pull practical jokes on us like this to throw us off.  The dress has a shitty flouncy hemline that allows tulle to show from underneath... very reminiscent of something you'd find for $29.80 at Forever XXI.  The neckline is even worse.  No one looks good in a turtle neck, especially if it is attached to your dress and in some heinous colour like teal.  Oh, and is that a black bra I see beneath the lace?
