I purchased Arpege by Lanvin purely because it was what my late aunt wore. I love the rich leather and soft flowery perume smell. I also love the bottle. It's a scent that is special but not overwhelming. Sphofisicated and feminine.
I have used Ivoire, Balmain, for years. It is no longer available much to my chagrin. I tried Arpege again, it was popular in the 60's and I find it pleasant, a bit strong, but it fades to a nice scent. Classy smell.
