How Can You Tell if a Perfume is High Quality?

To identify a high-quality perfume, look for a scent that is complex with a clear structure of top, middle, and base notes. The perfume should have good longevity, lasting throughout the day, and a noticeable sillage that leaves a trail. High-quality perfumes often use natural ingredients for a more authentic scent and have a higher concentration of aroma compounds with less alcohol.
