Yes I am a guy asking a question about perfumes and colognes.

Anyway here's the situation. My girlfriend's birthday is coming up so I was thinking of getting her a bottle of perfume (standard gift for women, since i'm never that clever with gifts anyway). And I was wondering if there was any perfume I could get her that would smell nice with another scent of men's cologne.
Maybe like for example Armani's Acqua Di Gio with Black Code, or something like that.


I collect men colognes so I wouldn't mind getting a new bottle for myself if it really compliments the perfume.
So yeah, feel free to suggest any two scents that you feel would go really well with each other.
