So-called “dress” jeans are usually dark denim or black, not faded, sanded, feathered, abraded or with holes. They do look great with dressy tops for women or collared shirts for men and nice shoes. My 28 y/o son actually wore his every night except formal night on our most recent cruise w/SS with and without a blazer. Honestly, I think they can look much better on some women than yoga pants and other skin tight pants I’ve seen worn at dinner.
