Ooh! My 3-5 perfumes would be:
First, which I've been wearing on and off since the 80s and always come back to.
DKNY Woman, which I first bought in New York. I wear it when I have to be a bit feisty at work!
Chanel 22, as every time I'm wearing it someone stops me to ask me what it is.
Annick Goutal's Eau du Sud, which reminds me of summer days in my childhood, as my mother used to wear something that smelled exactly the same as this.
I'd also include the original Ivoire, which has now been reworked into Another Generic Pleasant Smelling Scent, and has lost its depth and dirty edges.
SOTD is Vertine. Pleasant enough, in a toothpastey sort of way. Was in hospital this morning for a minor op and didn't want something that was going to remind me of it!
