In my thirties, I'm finding more and more fragrances irritate me. Jo Malone has become my go-to brand. I spent three months in London at the beginning of this year, and would visit the counter to try various fragrances. They are more "pure" to my nose than others.
Over time you find your favorites and since they are generous with samples, can begin combining fragrances. They offer suggestions for combinations on their site.
I'm enjoying the new Mimosa and Cardamom layered with Wood Sage and Sea Salt. I also own Blue Agava and Cocoa (scrumptious), Peony and Blush Suede, Grapefruit and Red Roses.
I have a candle in Blackberry and Bay. The scent is very pure.
The small size fragrance is $60. For a luxury brand, I think that's reasonable. They often come out with sampler sets this time of year.
