I got excited when I recognized somebody wearing L'Artisan's Veleur de Roses!
I didn't approach her right away and ask her though. I wasted until I got to know her (she works in my office), then when we were comfortable with each other, I asked her and I was right!
She was surprised that i knew what she was wearing b/c not many people know about her fragrance.
I now have an office fragrance buddy! It's a good feeling.
