Try to recall a time when wearing cologne was commonplace for both men and women. Put yourself in that time and place. Which ones did you like? Which ones made your nose wrinkle?
Which lingered long after the wearer had passed through?
For example, back when Old Spice was quite popular with men, when you were near someone wearing it, how did it make you feel?
Now consider a woman wearing Channel #5.
Your task is to write a story in which a character is wearing a distinctive cologne. That cologne must play a major role. For example, what if the burglar had been wearing the Channel? Or the rapist the Old Spice?
What images would your victim call forth?
Include as many sensory details as you can.
Have fun with this one.
