Generally, I'm terrified of shopping. I like the idea of being well-dressed, but I've always struggled to get anything that fits. I envy those that go into old vintage shops.
I feel like my figure is a challenge because I'm quite flat chested but I've got a booty so I've got to look for the right things.
Turning the heat up on the red carpet while still looking like a lady isn't as easy as it sounds. Too much va-va-voom, and a girl can look like she just stepped out of 'Jersey Shore.' Too little, and she'll look like a sister wife.
I can't walk in heels at all.
You leak sometimes. My pediatrician said, 'Can't you just wear pads under your clothes?' I said, 'You don't know the kind of clothes I wear on photo shoots.'
I got my heel stuck in a drain as I was crossing the street and cars were coming. It was really scary. A girl in heels in New York is a hard combination.
I like the challenge of dressing ladies in lots of different things.
Consumers around the world always want something unexpected and exciting, and that's what drives me. I love the challenge of reinterpreting my designs in new ways each season to keep the "prep look" modern and fresh.
I probably would never be caught wearing a baseball cap. Hats are difficult to me because they tend to be too big for my head. They don't fit right, and I feel ridiculous.
I have a hard time finding high boots that go up to your knee, because of the shape of my calves.
Pulling off a zebra-print dress can be challenging for some.
Ah, the intractable Canadian problem: Winter and finery are basically incompatible.
Growing up, I was very conservative in my wardrobe, so when I first joined the Pussycat Dolls, the biggest challenge was wearing those cabaret costumes. I didn't feel comfortable showing my body so much, showing my legs and butt, chest and midriff.
I would love to design a maternity clothing line. It is so hard to find stylish clothes for pregnant people... I would say 99 percent of the clothes I wore were not maternity because I couldn't find anything I liked.
Since I have that edgy, rocker-tomboy kind of vibe, it can be very difficult to translate my style for the red carpet.
Wearing a bold print gets harder as you get older. It's safer to stick to subtle prints or block colours. I have always found prints quite tricky. My daughter Carly, who is on the design team at Stella McCartney, is obsessed with them.
Growing up, I had trouble finding clothes because I was curvy, and so I would end up designing my own things.
I don't know - I think guys don't get as much credit as they deserve sometimes for how hard it is to put a great look together. It's so easy to just do a 'suit,' but to make it look a little different, it takes some effort.
I started by designing a sweater very close to the body, because I couldn't find any for myself.
I am very curvy, so the vintage stores suit me better than most designers. I just can't seem to give up crisps, or make my boobs shrink for that matter. Alas, I will never fit a size zero.
For me, in a world full of armies of stylists and makeup artists, what I think truly makes a fashion icon is how a girl dresses when she's off duty and she has to put her own looks together - no small challenge!
I love vintage clothes. But they don't love me very much. It is difficult to find anything that fits me because of my height, but if I do fall in love with something, I'll buy it and display it like a work of art at home.
