Yes - I do this. I rarely wear CdG #3, since it's basically a synthetic, floral, aromatic scent that is just plain weird. But I can't imagine getting rid of it. Yet.
I think a lot of CBIHP fragrances fall into this category as well. They're so intellectual and nostalgic. And yet I don't want a rush of emotions and memories from my childhood flooding over me when I'm rushing to get ready for work and I grab your SOTD. Not me. But for those quiet moments in life (meditating, home alone on a Saturday with no errands to run, etc) scents like these are essential. In these concentrated moments when I can really give a fragrance my full attention, I love trying the stuff at the back of my wardrobe.
