* A niche or indie brand: Many small perfume houses create unique scents with their own names.
* A custom fragrance: Someone might have created a fragrance for themselves or as a gift and named it "Logan."
* A mistaken name: You might be remembering the name incorrectly.
To help me find the perfume you're thinking of, could you please provide more information? For example:
* Where did you see/hear about it? (A store, website, friend's recommendation, etc.)
* Do you remember any notes of the fragrance? (Floral, citrus, woody, etc.)
* Was it a men's, women's, or unisex fragrance?
With more details, I might be able to help you find the "Logan" perfume you're looking for.
