Fragrance is such a personal thing that it's difficult to describe why you like it or not. All I can say is that 'Lovely', for me, is a beautiful, rich fragrance that is classic, feminine and very classy.
I don't usually buy into the whole 'celebrity' perfume thing either and initially I resisted this perfume, until an assistant one day insisted that I take a sample stick from her and told me it was 'Lovely' by SJP.
I was looking for a new perfume for my wedding day, so I took it upon myself to sample as many as possible before purchasing that special scent for my special day (I know it sounds corny, but I must admit, I did!). This is the perfume that won the job.
So for me, 'Lovely' takes me back to (what turned out to be) a magical and beautiful day, so it's special to me in that sense, but it's also just a jolly 'Lovely' smell (hee hee). I can't see me ever getting bored with it, as some perfumes do tend to become stale with time, but I think this one will always be a part of my perfume collection. Oh AND it lingers on my skin ALL DAY (or night), and I can't say that about many perfumes. I LOVE IT. But I think you may have guessed that already?!
