high end fragrance

Hey I am looking for a new fragrance. My budget is about 450 euros.
Wich brands have the highest quality ingedients of all.

Wow, that's a generous budget! There are so many great niche and designer brands; it would be hard to narrow it down to a few brands. I'd recommend you invest in several samples first, then decide from that point onward. The Scent Bar (luckyscent.com) would be my first stop. I love Guerlain, (some) Tom Ford, Chanel, Tauer Perfumes, Serge Lutens, Maison Francis Kurkdjian, Diptyque and so many more.

I second Guerlain, Chanel, and Serge Lutens and would add Amouage to the list too.
