Olivia Palermo is obsessed with blazers and owns many tailored jackets as they can change an outfit in seconds and thinks they're an essential item in any girl's wardrobe.
She said: "I'm obsessed with blazers! I love tailored pieces and blazers are great - they can be worn with anything and instantly change an outfit. I always try to wear one structured piece. I'm also into embellished pieces and gold and copper-toned metallics - although not everyone can pull those off."
Fashionista Olivia claims it's important to invest in good underwear.
She told Closer magazine: "Underwear is like clothing, you have to feel sexy and confident in it. I wear nude or black lace. I love Intimissimi's NERO collection - it taps into the trend."
The American brunette Olivia also says is a huge fan of British girls' style.
She said: "When I think of British girls, I think of a great little skirt and leather jacket. British girls have such an awesome edge. I love the fact that everyone, especially in London, is so expressive through their clothes."
