The question is - why do you feel the need to wear perfume. On the pull? You naturally stink otherwise? Fallen for advertising? Bit of a girl?
Nahh, I just like the smell of decent fragrances. Similar to the smell of different flowers or plants...for me it's a feel good thing. Maybe it helps release dopamine?
Whilst Barry suggests, it's nice to hear people say "oh that smells nice" or similar, but in no way do I wear for the benefit of others, it's purely for me. I don't actively go "on the pull" but that's rather limited at present any way
As for advertising, I'll be one of the last to fall for a purchase via advertising (I am heavily critical of a lot of advertising (see: SkyVegas Man) campaigns), unless it happens to be really good but even then it has to be something that really catches the eye in order for me to purchase directly from an advert in any medium.
