I have discovered my latest perfect one, that being Oud Ispahan but i want to sample others before i splash out on a big bottle of the OI. i am gathering my samples to help me make the decision. I have to say though. I am finding the longevity of OI is tenacious, it just keeps on giving, even when you want it to quit. Don't think i've ever possessed a fragrance as long lasting as this. Thats one of the things i am loving (and hating) about it. It stays as strong to the end as it did when i applied it. It's 3.07 am, and i applied it at 11.30 this morning. I almost have a headache from it. I do tend to spray too much fragrance, so i'd have to go lightly if i do splurge on a FB.
