Byredo is a creative unique take on scent experiences. Nice fruity fragrance at first, not too fruity, just right, perfect for unisex, dry down is woody, slight musk, not much vanilla. This reminds me of a softer more rounded Coco Chanel fragrance. Really smells nice, clean, fresh but mostly a winter fragrance but may be my signature scent. Patchouli is not too strong but definitely there. Don't be worried as this should have much appeal if not mass appeal. As the day goes on it gets more woody and musky, well balanced. Lasts for a long time, like easy 12 hours on me, even overnight. My wife loves it too. Doesn't really remind me of a library but still a great fragrance. Would recommend for a niche starter.
