Right now I'm leaning toward Mazzolari Lei, PG Intrigant Patchouli, or HdP Ambre 114. The decant of Lei is going the fastest of the three. But I never know for sure until I'm there, at the cash register. I tend to be rather spontaneous.
(((shades))) What a lovely way to remember your dad. Mine would have been 79 this past November. My olfactory preferences (orientals, especially ambers and smoky fragrances) are my daily tribute to (and reminder of) him. He adored those, but my mom likes LotV and other soft white florals. He tended to buy her what he liked, rather than what she likes. Ships passing, olfactorally speaking.
