Why It’s An Investment: Today, the Evelyne is regarded as a high fashion messenger bag, a timeless piece from Hermés. Its crossbody, hands-free and casual styling is on trend for everyday wear, and has become an iconic bag, alongside the Birkin and Kelly. Crafted in Clemence leather (a style that is most likely to hold its value), this piece makes for a classic piece that will never go out of demand. Characteristics: This black messenger bag is crafted of rich grained calfskin leather.
