The British model - who split from boyfriend, `Doctor Who` actor Matt Smith, in November - admitted she always decides whether members of the opposite sex would be a suitable pairing for her by their choice of footwear.
She said: "You can always judge a man by his shoes. I couldn`t tell you what makes a bad pair of shoes, but if I saw them I would just know."
However, any men hoping to impress the 22-year-old beauty may wish to avoid donning a baseball cap, as Daisy explained the sporty choice of hat "disgusts" her and she thinks the only person who can pull off the look is rapper Jay-Z.
Speaking as part of a shoot for men`s fashion website MrPorter.com, she added: "I like a good beanie hat on a man, but baseball caps disgust me - they`re so juvenile.
"If a man loves his baggy jeans and feels comfortable in them, he can wear them at any age, but I think that there`s an age limit of 14 for baseball caps. But if you`re a rapper like Jay-Z you can get away with it."
