Which designers do you love?
Una: [When it comes to] key items like shoes, sunglasses and handbags, we've got a lot of designer. I've got a pair of Jimmy Choo boots, an Alexander Wang bag and Chanel shades but they last for years. Everyday clothes we wear all highstreet.
What was your favourite red carpet moment as a group?
Mollie: Recently we went to Pride of Britain Awards and as a band I really liked the look of us.
Is there another girl group whose style you really like?
Rochelle: I like the fact that they Spice Girls could all be really different from each other. Sporty could wear a tracksuit and Posh Spice could be in Dolce & Gabbana; they were all really their own person. But, as a group, I don't think anyone does it better than Girls Aloud.
Who is your style icon?
Mollie: I like Olivia from The City, she always just looks so good!
What is the most stylish city you have ever visited?
All at once: LA, New York, Paris, Tokyo, Rome!
What was the first fashion treat you bought yourself?
Frankie: The first expensive bag I bought was YSL - I was so excited! It's a girl thing. Guys buy watches but girls by handbags and shoes.
Do you still have it?
Yes! I use it all the time, I love it.
Where do you love to shop?
Una: Selfridges because it has all the brands under one roof. I love to have variety when I'm shopping.
What is the best piece of fashion advice you have ever received?
Rochelle: Less is more. That's the best thing you can ever tell anyone. Also, whatever is in fashion always dress to your body shape.
What beauty product can you not live without?
Frankie: Carmex. I can't live without it. It is really simple, but I hate having dry lips. I can just shove my sunglasses on and as long as my lips are wet I am alright.
