Halle Berry in Versace: Oh Halle, Halle, what have you done? Too many trends – print, cutaway, sheer, asymmetrical – can and have spoiled a perfectly good dress. Va va voom Versace or no, this one is a fashion fail for the usually stylish Halle.
Rachel Weisz in Louis Vuitton: If Mrs 007 hadn't forgotten the bottom of her dress, she would have been on the best dressed list. Sadly, she did forget it and so she's on the worst dressed list. Imagine the dress with a plain skirt instead of the dotted panel – see what we mean?
Giuliana Rancic in Celia Kritharioti: This Goth horror is just plain ugly. A shame, because TV anchor Giuliana usually sticks to simpler and more flattering dresses. Lesson to take away: on the red carpet, stick to what you do best.
Julie Bowen in Halston: Modern Family's Julie Bowen picked a great colour for her fair colouring, but definitely not the right silhouette for her slim figure. The unflattering drape and volume makes sure the dress wears her and not the other way round.
Sienna Miller in Erdem: Sienna and Erdem have been triumphant on red carpets before this – but not this time. The pale, flowered top and skirt washes Sienna out and switches down her natural glam factor by several notches. Next!
Eva Longoria in Emilio Pucci: It's either a plunging neckline or a Joliesque pose, Eva. Not both. Both I, dare we say, a little Desperate Housewives-ish. With that hair and that dress, we almost mistook you for Kim Kardashian. Not a good look.
Kaley Cuoco in Katharine Kidd: Kaley's prom princess look, complete with bow belt, is anything but a Big Bang on the red carpet. And then there's the dark lip colour.
Katharine McPhee in Theyskens Theory: Another too low-too high sinner. That's a dress best left to models on the catwalk.
Debra Messing in Donna Karan: It's black but not beautiful. Debra's overwhelming ruffles, a too bare neckline and severe hair leaves us cold.
Emily Mortimer in Jenny Packham: We're all for a little bit of shine and sparkle but Emily's full metal jacket makes her look like a disco ball.
