If you’re thinking about buying a bag for its longevity factor (or the possibility of reselling it down the road) it’s important to consider how the fabric, hardware and color will look over time. Experts say to keep an eye out for heavyweight materials, durable zippers and stitching, equidistant and precise corner stitching and polished metal hardware, which will stand up to repeated use, and a finished surface that resists water and dirt.

A few other best bags can also increase a bag’s resell value. For instance, some classic bags are likely to go up in price simply due to inflation or scarcity, like the Chanel 2.55 Flap Bag that spurred a thousand imitations, or limited edition collections and colorways that go out of stock faster than others.

Another factor is the design of a bag, and whether it’s on trend right now or will likely stay in style for a while. Generally speaking, bags with a timeless silhouette or a vintage-inspired aesthetic will hold their shape and color longer than others.

For example, the Carl Friedrik Ashby leather tote is a timeless beauty with clean lines and pristine details that will only get better with age. The vegetable-tanned Vachetta leather develops a deep, rich patina as it ages, and the tote’s durable construction features equidistant, precision stitching, a smooth finish and sturdy, polished hardware. It’s the most expensive bag in our test, but its timeless elegance and lifetime warranty make it a solid investment.
