How many perfumes should I have to curate an exquisite collection that reflects my unique personality and enhances my olfactory experiences? Is there an optimal number that strikes the perfect balance between diversity and maintainability, or does the ideal quantity vary based on individual preferences, occasions, and seasons? Should I consider the range of fragrance families—from floral to oriental, and woody to fresh—when deciding how many to accumulate? Might it be prudent to include a signature scent that embodies my essence, while also incorporating various other fragrances that cater to different moods and events? Furthermore, how often should I refresh my collection to ensure that each bottle is cherished and appreciated, rather than relegated to the back of a drawer? Ultimately, is there a guideline or formula to follow, or does it come down to the personal enjoyment and the art of fragrance layering that resonates most with me?
