With its mixed bag guest list of new talent, A-list stars and celebs of yesteryear, the fashion sightings at the Oscars after party is a hot spot where the bad and the ugly far out number the good.

Marion Cotillard
Marion usually blows me away with her high fashion choices. She can pull off a lot of look, so when something is not great on her it’s kind of a big deal. The beaded top and intricately ruffled skirt are amazing on their own, but what is happening at the waist here? The drop waist black sash with white fabric "tied" in the middle makes this dress appear bulky. A sleek transition from top to skirt would have looked less cobbled together.

Kat Dennings
Someone needed to rescue Kat from this dress! The beaded cap sleeve and high collar merge with the lace neckline in a way that makes the star appear to be suffocated by an old lady hand-me-down. And that colour is terribly drab. The tousled updo, glowing skin and beautiful berry lip colour aside, there’s no saving this look. Period.

Kelly Lynch
Props to Kelly in the face and bod department, she looks amazing. But this outfit is a mess that completely distracts from that fact. Between the graphic lace, triangle bra top underneath and shorts-maxi skirt combo, there are way too many competing style elements working against each other. With more coverage on the bodice and a simple slit maxi skirt, less would have been more.

Joan Collins
My love for ornate embellishment runs deep, but the best of the best has a timeless quality. The detailing on Joan’s dress makes her look stuck in the '80s, especially with those mega earrings in place. I’d swap the legendary actor/writer into something equally glitzy but much more modern.

Jessica Chastain
By no stretch is this a picture of flat-out hideousness but this one makes the list simply because we’re so disappointed. The colour? Meh. The cut? It’s nothing to write home about. With her gorgeous mug, divine figure and covetable mane, this woman (last seen in A Most Violent Year) oozes A-list movie star and this dress is C-list, at best. We know you can bring it, Jessica!

Minnie Driver
Prints aren’t necessarily a popular red carpet choice, and we can see why. Sometimes they simply fall flat. While the colour palette and blossoming motif of Minnie’s gown are pretty they lack any real impact. If you’re going to do a bold floral, don’t take a baby steps, you’ve got to really go for it all the way! A bolder print in punchier colours on the star would have won us over.

Irina Shayk
The after party was packed with many stars rocking slinky, sexy, sheer looks. Rita Ora, Chanel Iman and Karlie Kloss, for example, were all amazing eye candy. But this one, being part gown and part transparent beaded body stocking, missed the mark. The key words here are body stocking. A sheer look has a major built-in OTT factor, especially on a model-perfect figure. Pushing the envelope with unusual tailoring is not needed.

Marisa Tomei
Navy plus pants plus feathers should add up to a look I love. The result however is a letdown, mostly due to those massive trousers. Having them either tailored straight from hip to hem or inverted to be wide leg culottes (yes!) would have saved these out-of-proportion pants.

Marley Shelton
This, ladies and gentlemen, is a lesson in wrong dress at wrong event. Anything associated with something as formal as the Oscars, or say a wedding for us mere mortals, demands a much more formal look. The aim should be for glamour and elegance, not a disco-appropriate flash. A slim-fitting floor-length skirt on this would have met the dress code.

Malin Akerman
Seriously sheer dresses were majorly trending on Oscar night and with something risqué comes fashion risk. One must choose what and how they reveal carefully. Malin’s netted dress with extreme plunging neckline over high waist briefs leaves little to the imagination. A little more coverage, whether by way of a higher neckline or larger opaque underpinnings, would have gone a long way to making this an elegant gown.

Jared Leto
Even Jared’s steely gaze can’t mesmerize us into un-seeing what going on below the beard. Pastel wouldn’t have been problem if the tone wasn’t so washed out. I put my foot down on the blocky white shoes, though. A more traditional shade, soft grey perhaps, would have helped be create a seamless look from head to toe for the Academy Award-winner.

Andie MacDowell
This dress is giving me some serious bad bridesmaid vibes. Besides featuring unfortunate hues (shades of brown should look luxe, not like tea stains), the asymmetrical and draped hem on Andie’s dress is too bottom heavy. She would have glowed in a rich chocolate metallic, and much less fabric.

Kylie Minogue
Leg-baring slits have been popular on the red carpet of late, but there’s an unspoken rule about them. The idea is to show a hint of leg, not the whole limb. Kylie’s strategically-place hand can’t hide the fact that this slit is cut too high and too wide, giving away too much. Side note: having the shoulder straps and slit on opposite sides would have been better for balance for the singer.

Lisa Bonet
Given that fringe is currently all over the fall/winter 2015 runway shows, Lisa is ahead of the curve here in some ways. The skirt portion of this dress gets two thumbs up for being chic and modern. But that is so not the story with the top half. The over-sized shoulder adornment and corset on the top half appear costumey and dated. A restrained version of just one of those details would have been the perfect accompaniment.

Zoe Kravitz
In a "like mother, like daughter" happenstance, Zoe showed us that she gets a bit of her fashion sense from mom, Lisa Bonet. The exaggerated mesh is cool and pretty against the Divergent star's caramel skin, but the fact that it looks like it was thrown over a flesh-toned bodysuit isn’t cutting it. Lining this dress, even to mid-thigh, would have eliminated the "I just arrived from a day at the beach" look while maintaining the edgy look.

Chloe Grace Moretz
The good news is that an Oscar after party is a second chance to wow the fashion world in one night. The bad news is that Chloe wasn’t able to recover from the Granny curtains she wore at the show. Even with a wide belt cinching her in, the voluminous sleeves and a double-tiered skirt creates an awkward diamond shape where an hourglass should be. Shorter sleeves would have highlighted her figure.

Jaime King
Jaime’s certainly got the mama-to-be glow going on, but the inner glow of the star can’t blind us to this no-no. The swirling floral print of this hippie chic dress is too reminiscent of vintage upholstery. Done over in crisp black and white would have given this flowing gown a contemporary twist.

Carla Gugino
Whatever your shape, clothes are meant to balance proportions. When all goes according to plan, the right neckline, waistline or hem can make you look leaner, slimmer and taller. And on the flip side, the wrong details in the wrong place will work against you. That’s what happened to Carla. Throwing a bunch of off-centered beading over a one-shoulder dress makes her look asymmetrical. Keeping the beading centered would have helped provide balance.

Brie Larson
Smart and funny, Brie is one of my favourite up-and-coming young stars, but she’s been aged beyond her years in this Victorian goth mash up. I’m not a fan of the width of the large skirt and I have zero love for that big ol’ bow either. Finishing this with a column skirt or pants would have been improvements that felt fresh.

Ashley Greene
Even a dress with a lot of peekaboo factor can come across as heavy looking. The olive colour and over-sized lace work together to create a dress that looks like it’s weighing Ashley down. A tighter weave and slimmer fit over the skirt would have been better suited to the Twilight star's slim frame, and I’d chop the hemline to elongate her legs while we’re at it.
