As someone who chose a nom de plume based on Le Parfum de Therese, I feel able to address with passion your question. If you love the work of Edmond Roudnitska, you will love Le Parfum. The leather is the signature leather note in all his fragrances, hardly dominant. All notes play well together here. The vetiver is very tame.
I discovered Le Parfum by accident. I went to the FM store in Paris, shortly after it opened. When I sniffed Le Parfum, I became teary and told the SA that it smelled like my grandmother. She asked what fragrances my grandmother wore. I mentioned Miss Dior, and the SA smiled. And so I learned about M. Roudnitska.
Do try it.
