Way too many, probably over 50. As another poster mentioned I have a tendency to also use them as room sprays, and if a friend or someone is over and mentions how she likes one I tend to just give it to her bc I am not really super in love with any of them at the moment. I need to stop buying perfume though, it's like a weird addiction for me, the second a new one comes out I have to smell it and if I even remotely like it I'll buy it.
Last time I count I owned over 50 bottles. The sad part is, I hardly ever wear perfume these days. The oldest bottles are Coco Chanel and Jean Paul Gaultier and they are, I kid you not, 10 years old. I know that perfume doesn't last forever but I cannot throw them away, it feels like sacrilege. Besides, they still smell just like the first day.
My favorites are:
-Coco Chanel
-Chanel No.5
-Fragile by Gaultier
-Dolce Vita by Dior
-Rush by Gucci
There's a few more but I can't think of them right now.
I only have one that I wear, D&G Light Blue. But I did ask for Givenchy Play or Burberry The Beat for Christmas. GREAT tip about storing in the dark!
