If you want your fragrance to remain unchanged throughout its entire lifecycle, consider springing for a linear fragrance . But if you're leaning more towards complex layers and a scent that will evolve over time, try using non-linear fragrances.  It's important to note, however, that not all linear fragrances are cheap and low-quality. Finding the best one for you may include a little bit of trial-and-error, but shouldn't break the bank.
