Whatever it is that sways you, it often takes years and countless spritzes to find that one perfume you return to time and time again: your signature. It's the perfume that allows your friends to pick you out in a room of hundreds; the one which earns you the most compliments on your morning commute and which you always make a beeline for in Duty Free. But fragrance is also much more nuanced. Research has found that scent is intrinsically linked to memory, people, places and experiences, making perfume less aesthetic and more of a meaningful addition to your daily wardrobe.
