I was sent a decant of this, and truthfully, I was not eager to try this. In the decant, the sandalwood and musk seemed to almost overpower the rose, which I didn't enjoy.
I finally sprayed it on, immediately noticing that it had decent sillage. I got rose at once, but also with that sandalwood, so I decided to let it do its thing and ignore it.
About 10 minutes later, I unexpectedly picked up this massive whiff of a slightly sweet, yummy rose. Not in-your-face sweet, though. This is a little honey-sweet. With vanilla. Yums.
After about an hour, it calms down slightly into a gentle, but still vibrant, rose mixed with mostly sandalwood, backed by musk, amber, and some vanilla. It comes across as trying to be creamy, but never really gets there. It also has a more masculine, boozy vibe, which could be nice, depending on your preference.
5 hours in, and West Side becomes rather muted. It no longer envelopes me, but I can catch whiffs of what is now a deeper scent, that seemed a bit more vanilla cake-like. I would say it fades completely after 6 hours on me.
As stated above, sillage was good. I sprayed once in the hollow of my neck, and once just above each elbow bend, and for the most part, it felt like I was constantly enveloped in it.
I mostly like this, but I think the decant that I have is more than enough for me. I'm not too partial to wearing a scent which, on me, leans on the masculine side. It is still a lovely, lovely perfume though.
