Since acquiring a tester bottle (scent unsniffed) of La Perla J'AIME, I've worn it a few times. I need to be honest. I don't really like this perfume. The first night I wore it, I actually woke up in the middle of the night wanting to wash it off--there seemed to be something off in it in the way in which celebrity scents however well-intended are often "off". I wasn't sure why I did not like it, but it smelled somehow discordant to me.
After a few more wears, I think that I've figured it out: it's the musk which makes this perfume slightly dirty and skanky at the same time that it aspires to be a gourmand delight. A comparison to Van Cleef & Arpels ORIENS might be helpful. ORIENS is also sweet and voluptuous, but there is no dirtiness or skank involved whatsoever. ORIENS is more like a treat, while J'AIME is something of a chore for me to wear.
I do very much like the opening of J'AIME, but I grow tired of it quickly and do not reach for the bottle in the way that I reach for perfumes beloved to me. Perhaps my bottle is bad, but the liquid was pink when it arrived. After a few weeks it had turned brown, and now it is nearly clear. No, I did not leave the bottle out in the light. I have kept it in the box, and the ambient temperature has been moderate, so something may simply be wrong with the composition of this perfume. It boasts (ha ha) BHT among its ingredients but that's obviously not enough to hold the whole production together because mine is not pink at all.
In the end, I should say that this perfume may work well for those who like musky perfumes along the lines of L'AGENT PROVOCATEUR or NARCISO RODRIGUEZ or SARAH JESSICA PARKER. But be advised: this one is also rather sweet in addition to being slightly skanky.
