I'm glad you like the Millesime Imperial, its one of those colognes that ladies love. I thought I should also recommend Body Kouros by YSL. It got me a few compliments yesterday from girls on campus. I'm 21 so that's an idea of what age group its more suited towards.
Creed colognes are very good, as are Bond no. 9 colognes. I'd recommend Millesime Imperial by Creed, Green Irish Tweed by Creed, and New Haarlem by Bond No. 9
