The 28-year-old model has confessed she is freaked out by the fastenings but has had to learn to control her acute fear because of her job.

She explained: "I most dislike buttons - they freak me out a bit! I used to have a slight phobia, which I've had to work on because of my job."

The blonde beauty - who is close friends with fellow model Alexa Chung - also doesn't let her fear impact on her hobbies so the stylish pair can go vintage shopping together.

She said of one particularly successful spree in Dallas, Texas: "We went to this fantastic street and found an amazing shop called Dolly Python - it had the best denim shirts, cowboy boots and I found the greatest body suit. I wore it to my hen do. Alexa's got a great eye for that sort of stuff. She bought a lot of high-neck tops."

Poppy - who is the older sister of Cara Delevingne - also shared her top style tips and believes it's important to "bring a sense of humour" to any outfit.

She told Vogue magazine: "You always have to enjoy what you're wearing and bring a sense of humour to it. To me there's no method to the madness, just have fun with it.

"Diversity definitely makes the best wardrobe- you want to look in and see a range so you can always dress for your mood."
