Aerin Lilac Path Perfume by Aerin This delicate fragrance from Aerin blends floral and fresh accords for a gentle delicate scent that immediately brings to mind the aromatic soft purple buds of a lilac bush. Aerin Lilac Path introduced in 2013 is straightforward with a relatively simple construction yet its smell is intoxicating and addictive. First and foremost it offers the scent of lilac a dainty and spring-like blossom with a fresh undertone.
