Nick: “Sienna’s a style chameleon. She looks as hot walking down the red carpet as she does hanging out at a festival or walking her dogs but, for me, she’s sexiest when she’s off duty.”
Verdict: Dressed down
Raef: “Sienna is the perfect picture of understated elegance in this red dress, but she resembles a hillbilly in that playsuit and pirate boots combo.”
Verdict: Glammed up
Mark: “The festival look has been thrown together, but the red dress is flirty, fun, and exudes subtle glamour. Her natural beauty dazzles on the red carpet.”
Verdict: Glammed up

Nick: “The yellow dress is flirty and sexy, just like Cheryl, but the tracksuit definitely has a touch of Vicky Pollard about it.”
Verdict: Glammed up
Raef: “I love the simple dress and I think she’s picked perfect accessories. But Cheryl, purlease, tracksuits should only be worn to the gym.”
Verdict: Glammed up
Mark: “The dress is short and sexy, and Cheryl can carry it off. But she looks chavvy
in the tracksuit.”
Verdict: Glammed up

Nick: “I like Victoria’s polished look, but it’s a welcome change to see her dressed so casually. She looks surprisingly hot.”
Verdict: Dressed down
Raef: “I like a lady to look like a lady. I fully approve of Victoria’s red-carpet couture, but in this baggy outfit, she looks like she’s robbed a teenage boy’s wardrobe.”
Verdict: Glammed up
Mark: “Her Marc Jacobs dress is far too fussy. Victoria’s casual look is refreshing and it reminds me how naturally pretty she is.”
Verdict: Dressed down

Nick: “Kate has an amazing figure. I still dream about her in that black catsuit in Underworld! She looks great in anything, but looks more confident dressed down.”
Verdict: Dressed down
Raef: “With her English-rose complexion, she looks a bit washed out in this yellow dress, but glamorous nonetheless. Jeans are unbecoming on a girl.”
Verdict: Glammed up
Mark: “She’s opted for a brave colour with this dress, but her casual look is cool and sexy.”
Verdict: Dressed down

Nick: “The feminine dress and quirky hat are Carrie through and through. When she’s not trying to be a style icon, comfort and casualness are clearly SJP’s priorities and it works.”
Verdict: Dressed down
Raef: “The dress is elegant and understated, but the jeans are horrid. Urgh.”
Verdict: Glammed up
Mark: “Just like Carrie she’s stylish with an eccentric touch when dressing up, but dressed down those jeans are drowning her tiny frame.”
Verdict: Glammed up
