Unisex occasions
Unisex perfume for formal dinners
A unisex perfume can suit a formal dinner if the exact fragrance is familiar and restrained enough for shared dining. The label itself says nothing about formality or projection.
A HUME Fragrance buying guide

Choose for the table
Consider prolonged close seating and food aromas. A grand dress code does not require a loud scent.
Evaluate texture
Soft woods, florals or freshness may interest you. Try the finished fragrance before linking any note with elegance.
Keep preparation simple
Use a tested application and avoid layering unfamiliar products before dinner. Omission is reasonable where fragrance is unwelcome.
Try this before you buy
Choose your dinner candidate by later character and considerate presence after setting aside gendered labels.
