My long time buddy got a promotion letter yesterday. He finally became the regional manager after many years of hard work. So, he invited few of us to celebrate with him

I want to buy a present perfume for him. Any suggestions? He's single, late 20s, sometimes need to meet clients outside.

Budget - none as long as it's worth it. Cheap or expensive doesnt matter as long as nice smell.

Bleu de chanel? Dior elixir? SWY? Whats your preference?
