Should I change perfume with the seasons
Changing perfume with the seasons is optional. Keep a favorite if you still enjoy it and can wear it considerately; explore another direction only when it adds a useful experience.
A HUME Fragrance buying guide

Identify a genuine gap
A different mood, routine or preferred texture is a clearer reason than the calendar alone.
Retest what you own
Your current fragrance may already fit the new setting. Compare later enjoyment before assuming it needs replacement.
Keep purchases proportionate
Samples can answer seasonal curiosity without requiring several full bottles. Choose quantity around expected use.
Try this before you buy
Write one specific thing a seasonal addition would provide that your current favorite does not.
