( CNN ) -- The Duchess of Cambridge 's style has long been a topic of conversation . ( Remember that see-through dress she wore during a 2002 charity fashion show at the University of St . Andrews ? ) But British Vogue is taking the world 's fascination with Catherine 's closet a step further . In its February issue , the magazine details everything from the average diameter of Kate 's curls ( 25 millimeters ) to the average number of teeth she exposes while smiling ( 8.6 ) . We already know she fancies labels such as Alexander McQueen and Jenny Packham , but now we can say , with certainty , that she dons blue more than any other color , and she wears boat necks to 42 % of the engagements she attends . And while her style choices can influence sales -- a phenomenon dubbed the Kate Effect -- designers such as Roland Mouret say it 's not so cut and dried . `` The kind of people who like Kate 's style are not the kind to rush out and copy her dress , '' Mouret told British Vogue . `` You do n't see hundreds of women running around looking like her . To be honest , we 're more likely to get orders on a dress that Kim Kardashian 's worn . ''
