Getting started
How many perfumes do I need
You do not need a collection to enjoy perfume. One fragrance can be enough if you like it in your usual settings. Add another only when you can name a specific need your current choice does not cover.
A HUME Fragrance buying guide

Start with actual use
If you wear fragrance occasionally, one well-chosen bottle may cover you for a long time. If you wear it daily in very different settings, a quieter daytime option and another evening choice might be useful. Neither arrangement is a rule.
Distinguish variety from duplication
Two fragrances that feel almost identical may add less variety than a few contrasting samples. Before buying another bottle, explain what it contributes: a different mood, occasion or scent direction.
Let usage guide the next purchase
Notice what you reach for over several weeks. A wish list can grow faster than your use. Sampling a new direction is a smaller commitment than buying another large bottle simply because your collection looks incomplete.
Try this before you buy
List your current bottles and the occasion each covers. Mark any real gap before adding another.
