In the era of online shopping and ever-more varied cuts, choosing a pair of jeans in your size can quickly become a headache. Between slim, straight, tapered, flare, mom, or bootcut fits not to mention the different rise heights—it’s increasingly difficult to navigate. Add to that the size variations across brands (American, French, Italian…) and you’ll understand why a jeans size guide has never been more valuable. Ill-fitting jeans mean daily discomfort, a silhouette that isn’t flattering, and often a series of returns. It’s also a waste of time and an avoidable source of frustration.
