I have always been against buying eau de toilette for fear that the scent will have disappeared by lunchtime. But my views were recently challenged when I met Dominic De Vetta, Jo Malone's Global General Manager. He explained that EDTs range from 9 - 15% concentration, while Parfum (EDP) can go from 11 - 20% meaning you can have an EDT which has more concentration of fragrance, in other words will last longer than an EDP.
