The discovery set was perfect since I was able to try all 5 fragrances without committing to a full size bottle. I really liked all 5 fragrances but I LOVE "IF". In the past I read a lot of reviews with the attitude of "Yeah, Right" but I have had so many people, men and women, stop me and ask what I'm wearing when I wear IF. It's not too strong and doesn't give me a headache. I think the hard part with ANY scent is to find one that blends perfectly with your own chemistry. For me it seems as though IF is that scent. The fact that's an oil means it doesn't evaporate and your left with an empty memory but rather you habe a wa memory when you touch those points where you applied. I did purchase full size bottles. This is NOT your drug store or even department store perfumes that you keep reapplying. Once you apply them, they are there, They aren't greasy at all.
