Baby, it’s cold outside but that’s not a good look, plus winter white is hard to get right and more.

Oprah
More "oh no" than "aha," this dress proves that impeccable fit is the key to successfully pulling off a bold colour. We're having a major issue with the tailoring on the top half. A deeper scoop neckline and more room for the girls would have turned this one around.

Audrey Tautou
French women rarely make a misstep but this starkly trimmed shirt detracts from the pretty floral skirt. A solid black shirt and more casual styling, with open collar and rolled up sleeves, would have been très belle.

Felicity Jones
Felicity Jones, the Oscar nominated actress for her role in The Theory of Everything, could use a tutorial on mixing textures. Opposites tend to attract, but the sequin turtleneck and ultra matte dress make her look like she threw a simple sundress over a disco outfit. A top with less embellishment would have added a just-right hit of sparkle.

Cynthia Nixon
Former Sex and the City star Cynthia Nixon took the winter white look to a new place...and we'd like her to bring it back, please. It's all good from neck to ankle, but the matching booties have got to go. Winter white needs a depth of hues to excel, so charcoal or silver footwear would have been more chic.

Penelope Mitchell
When you play a witch on a TV show full of vampires, Mitchell should know when something bites. Not since the days of Working Girl have we seen a more distressing skirt suit and footwear pairing. Only with sharp tailoring, zero frills, and polished footwear is wearing a suit and boots is a possibility.

Cobie Smulders
Smulders may be a part of the winning Captain America franchise, but there is nothing super about this look. A voluminous top and skirt can co-exist, but the fit of this boxy top is too far on the slouchy side. Cobie: Next time, try it with a pencil skirt.

Blythe Danner
We hate to pick on Gwyneth's mom, but this look could use a little Goop-ing up. Trading in the traditional cardigan for a belted wrap style would have defined proportions while redefining Grannie Chic.

Octavia Spencer
A flirty pleated skirt, fresh colour and fun embellishments (shells and starfish, why not?) makes the bottom half of this dress great. But the large collar and sheer shirt/lining combo up top are less desirable. A wide V neckline would have given this frock a pretty vintage flair.

Saoirse Ronan
Oversize menswear outerwear was a big trend on the fall/winter runways, but there's a fine line between a fit that looks slouchy and one that leaves you swimming in fabric. Shortening the cuffs and hem of Saoirse's coat would go a long way to making it fit to a T.

Hailee Steinfeld
Hailee is starring in Pitch Perfect 2, opening soon, but this look needs some fine tuning. A crop top, body chain and long skirt over pants is a lot of look that's too "look at me." Eliminating just one of those details would have lead to a more effortless outfit.

Joan Cusack
Wrapped in a blanket scarf (or is it just a blanket?), our favourite TV homemaker looked more bundled up for a night on the couch than dressed for a night on the town. Wearing a voluminous scarf demands a balance of proportions, straight leg jeans would have been a better choice.

Analeigh Tipton
This starlet has a willowy frame that can wear anything. Well, almost. Done right, a sweater dress could add some shape to her slim figure, but instead this shapeless ivory dress ends up looking like a sack. We'd swap it for a marled knit turtleneck dress, layered with a long vest for polish.

Kristen Wiig
We couldn't be bigger fans of this funny girl, and star in the upcoming all-female Ghostbusters cast (whoop!), but we're not big on this outfit. A slew of pale shades head to toe makes Wiig look washed out. A top in a rich hue, like burnt orange, would have brought this look back to life.

Q’orianka Kilcher
New face Kilcher (she's shooting a flick with Diane Kruger and Norman Reedus at the moment, NBD) is a total knockout. But her coat and boot combo is a little too aggressive. With a statement coat on your shoulders flashy boots aren't needed, a simpler pair would have fared better.

Nicole Kidman
Wherever you are on the vertical scale, the proportions of your clothes are essential to looking polished. Exhibit A: Kidman's cropped pants look two inches too short on her tall figure, exposing more calf than ankle.

Yolonda Ross
Ross, most recently seen in the TV movie Whitney, is demonstrating an important lesson about ponchos. All that fabric can easily look overwhelming. Never sacrifice coverage for length. Looking long and lean is the goal, choose one that hovers at hips if you're on the petite side.

Andra Day
Day, a singer-songwriter, has a retro beauty look and hair style down pat, but the dedication to one colour isn't working. And you can't throw a body chain over just any outfit. A sleek LBD have been a sharp contrast and modern update that would work with her signature style.

Judith Godreche
Wearing socks with shoes is a look that pops up on the catwalk but can be tough to pull off in real life–even if you're a Parisian actress and director. The main problem here: the white sporty-looking ankle socks. A fancier stocking might have sent this style off on the right foot.

Haley Lu Richardson
Not a great first impression when your outfit immediately calls to mind an infamous movie costume (we're looking at you, Sandra Dee). Had newcomer Haley Lu chosen black wide-legged trousers over the skintight shiny leggings, this knit crop top would have looked hot instead of hilarious.

Charli XCX
Not sure what's worse here (is it the generous silhouette or the weird shading?) but this leather and lace look is wrapped up in all kinds of ugly. A solid colour and strict tailoring would have given this lace dress the rock vibe it's searching for.
