From Helen to Katy, see which celebs made this week's list.
Best and Worst Oct week 2
Keira Knightley looked stunning in this beaded cream Chanel dress, which was demure and sexy at once.
While Keira's dress was a style hit, Gillian Anderson had a major fashion mishap at the same event in an ill-fitting mint green dress with frayed hemline.
Girls Aloud's Walsh looks chic and pretty in a camel-hued (the colour of the season) asymmetrical dress at the launch of her jewellery range in London. If she'd ditched the black tights for bare legs, this great ensemble would look even better.
Quelle horreur! Cotillard is usually a super savvy dresser, but this leather corset (which she's busting out of), messy hair and vampy lip made the overall look more tramp than triumph.
It seems Helen Mirren looks better and better every time she steps out on the red carpet. This red wrap dress is super flattering on her shape and we love how she added some extra glamour with a jewelled brooch.
The Kardashian sisters might thinking showing up in matchy-matchy black and white jungle print dresses is cute, but we think it's tacky. Sorry, girls!
Not only does the Prime Minister's wife look lovely in this understated floral frock, but it's hard to believe she gave birth mere weeks ago.
We love a fashion risk-taker, but the royal blue hotpants, tap shoes, gold metallic parka, studded bag and bowler is way too much at once, especially for dinner.
The presenter's been making the rounds at Paris Fashion Week but this Vuitton look she sported at the show is our favourite way to do schoolgirl chic: a floral print halter dress topped off with a sensible jumper.
Charlotte's street-style look is super cute... until you get to her strange, suspender-style tights, which don't match at all and take the outfit from laid-back to tarty.
