Penhaligon's Iris Prima is the winner. As I suspected, DH really didn't like Halfeti. Nor did he care for Mitsouko. Mitsouko is like fine Scotch, it's an acquired taste to my way of thinking. Half the time I love the whiffs I catch of it, the rest of the time I can live without it. I could definitely see it growing on me. Dior Dolce Vita is nice but doesn't blow me away like Iris Prima.
As for scents I've loved over the years, I've been very fickle and can't remember most of what I've enjoyed. I recently tested and purchased Wildfox and I still like that though not as much as Iris Prima. I'm definitely asking DH for Iris Prima for Christmas.
