The denim will stretch quite a bit. We suggest buying them tight, even sizing down, as they will stretch.The Cast in Coast has never had stretch in the first fit or the Cast 2 fit. The Cast 2 fit is skinnier from the knee down and about a half size smaller in the waist. There are also different stitching and rivet details. All "Coast" denim has always been non-stretch 100% cotton selvedge.
